Question

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?

Answer 1

Given,
Walk + Ride = 33 minutes....(i)
Also,
Walk + Walk = 45 minutes
2* Walk = 45 minutes
Walk = 22.5 minutes....(ii)
(ii) in (i)
22.5 + Ride = 33 minutes
Ride = 10.5 minutes.
Ride + Ride = 2*10.5 = 21 minutes
Hence it would take 21 minutes to ride both ways.
Hope it helps
