Question

Mohan walks a certain distance and rides back in 6 hours and 15 minutes. If he walks both ways he takes 7 hours
and 45 minutes. If Mohan rides both ways the time which he will take will be:
(a) 4 hours
(b) 19/4 hours
(c) 9/2 hours
(d) 17/4 hours
(f) None of these

Answer 1

Answer:

If Mohan rides both ways he will take option b) 19/4 hours.

Step-by-step explanation:

Given that time taken to walk both ways = 7 hrs and 45 minutes = 465 minute

=> time taken to walk single way = 465/2 = 232.5 minutes

Time taken to walk one way and ride one way back = 6 hrs 15 min = 375 min

=> time taken to ride one way only = 375 - 232.5 = 142.5 min

=> time taken to ride both ways = 142.5 x 2

= 285 min

= 4 hrs + 45 min

= 4 + 3/4 hrs

= 19/4 hours

Hence If Mohan rides both ways he will take option b) 19/4 hours.
