A. 7hours 45min
Feedback Given that time taken for riding both ways will be 2vhours lesser than the time needed for waking one way and riding back.
Therefore,time needed for riding one way = time needed for waking one way - 2hours
Given that time taken in walking one way and riding back = 5hours 45min
Hence, the time he would take to walk both ways
=5 hours 45min + 2hours
=7hours 45min
