Phani and gopi decided to have a car race. Initially Phani was 20 miles behind gopi’s car. Both of them took the race in the same direction along the same route. Phani was travelling at a constant speed of 68 miles per hour, while Gopi was travelling at a constant speed of 60 miles per hour. How many hours will it take for Phani to overtake and drive 8 miles ahead of Gopi?
Phani has to travel 20 miles first to catch up Gopi. Then, he has to travel an additional 8 miles to be ahead of Gopi. Phani has to travel a total of 28 extra miles relative to Gopi’s car.
Relative Speed of Phani with respect to Gopi = 68 - 60 = 8 miles per hour.
Time taken for Phani to cover 28 extra miles compared to that of Gopi = Extra Distance / Relative Speed of Phani with respect to Gopi = 28/8 = 3.5 hours.
Rampual was working for a multinational company. The pressure of work in the company was too heavy due to seasonal sales. Rampaul decided to go weekend trip with his wife for relaxation. Husband and wife decided that the proposed trip should not exceed 8 hours driving in a day. They decided to maintain the average Speed of forward journey to 40 mph. Due to traffic on Sundays the return journey average speed can only be at 30 mph. How far the couple can select a picnic spot?
The forward and return journy speeds are x and y respectively : 2xy / x+y
Then average speed = 2x40x30 / 40+30 = 2400 / 70 = 240 / 7 mph
Total Travel Time is 8 hours. So total distance the couple can plan = Average Speed x Total travel Time = 240 / 7 x 8 =1920 / 7 = 274 miles
274 miles should be the total distance that can be covered including forward and return journeys,the picnic spot has to be at 274 / 2 = 137 miles
Rambabu is driving a Honda Unicorn Power bike at 80 km per hour. However being Diabets patient, Rambabu could not travel continuously. He takes small breaks each of 2 minutes for every 15 minute of his drive. How much distance Rambabu will cover in 90 minutes?
For every 15 minutes he takes a rest for 2 minute.
Hence for 90 minutes of drive he would require 12 minutes of rest. In effect he will be traveling for 90 - 12 = 78 minutes.
For 60 minutes he covers 80 Km.
For 1 minute he would cover 80/60 Km.
For 78 minutes he would cover (80/60)78 = 104 Km
The church in the US has a big clock tower and is said to be over 300 years old. Every Monday 10.00 A M the clock is set by Antony, doing service in the church. The Clock loses 6 mins every hour. What will be the actual time when the faulty clock shows 3 P.M on Friday?
Total hours from Monday 10.00 AM to Friday 3.00 PM =101 HOURS
The clock loses 6 minutes every hour.In 101 hours it will lose 101 x 6 =606 minutes. ie 10 hours 06 minutes.
To find the actual time, calculate 10 hours 6 min backwards from Friday 3.00 PM which is 4:54 AM
Hence the actual time would be 4:54 AM when clock shows 3.00 PM on Friday.
A Maruti Swift car started from Chennai towards Mumbai at 7 am. A Tata Indigo car newly purchased started from Chennai at 10 am towards Mumbai and the second vehicle was able to cross the first vehicle at 6 pm on the same day. If Tata Indigo was running at an average speed of 80 km per hour what would have been the speed of Maruti Swift car?
Tata Indigo car had taken 8 hours to cross Maruti Swift running at 80 km/hour.
Distance covered by Tata Indigo in 8 hours = 80 x 8 = 640 km
This distance has been covered by Maruti Swift in 11 hours (as it started at 7 am and was crossed by Tata Indigo at 6 pm)
So average speed of Maruti Swift - 640 /11 = 58.18 km/hour
The Truck started from chennai towards Kolkata at 6 am and it was running at an average speed of 60 km per hour. Another Truck started from chennai at 8.30 am and crossed the First truck at 4.30 pm. What is the average speed of secondTruck?
Two trains from the points A and B moving in opposite direction , at the point they meet the second train travels 120 kms more than the first. The speeds are 50kmph and 60kmph respectively find the distance between A and B?
Train A speed 50 kmph and train B speed 60 kmph then both start opposite directions.So After 12 hours they meet at that point on that time ,according to question the spped of B is 120 km more than A i.e A 's distance is 600 and B's distance is 720 .so the distance between A and B is 1320.

If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319 ?
log 0.317=0.3332 and log 0.318=0.3364, then
log 0.319=log0.318+(log0.318-log0.317) = 0.3396
In a basket 150 packets consists of 1kg packets and 2kg packets. Total weight of basket is 264kg. How many 2kg packets are there ?
x= 2 kg Packs
y= 1 kg packs
x + y = 150 .......... Eqn 1
2x + y = 264 .......... Eqn 2
Solve the Simultaneous equation; x = 114
so, y = 36
My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W. What is the local time when my plane landed?
The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20 hours = 6: 40 AM
A plane moves from 9°N40°E to 9°N40°W. If the plane starts at 10 am and takes 8 hours to reach the destination, find the local arrival time ?
Since it is moving from east to west longitide we need to add both
multiply the ans by 4
convert this min to hours ie, 5hrs 33min
It takes 8hrs totally . So 8-5hr 30 min=2hr 30min
So the ans is 10am+2hr 30 min
=>ans is 12:30 it will reach
A fisherman's day is rated as good if he catches 9 fishes, fair if 7 fishes and bad if 5 fishes. He catches 53 fishes in a week n had all good, fair n bad days in the week. So how many good, fair n bad days did the fisher man had in the week
Go to river catch fish
take what is given 53
good days means 9 fishes so 53/9=4(remainder=17) if u assume 5 then there is no chance for bad days.
fair days means 7 fishes so remaining 17 --- 17/7=1(remainder=10) if you assume 2 then there is no chance for bad days.
bad days means 5 fishes so remaining 10---10/5=2days.
So 4 good, 1 fair, 2bad.= total 7 days.
Y catches 5 times more fishes than X. If total number of fishes caught by X and Y is 42, then number of fishes caught by X?
