arithmetic - i walk a certain distance and ride the car back taking a total time of 33 minutes i could walk both sides in 45 min how long would it take me to ride both ways - skillgun

Time taken in walking a certain distance
from X and Y = 22 1/2 min
Time taken in riding the same distance
= 33 - 22 1/2 = 10 1/2 min
It will take 21 min to ride both ways.
