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
