| A man takes 5 hours 45 min in walking a certain distance and riding back. He would have gained 2 hours by riding both ways. Find the time he would take to walk both ways.

A. 3 hrs 45 min

B. 7 hr 45 min

C. 12 hrs 12 min

D. 6 hrs 45 min

### Right Answer is: B

#### SOLUTION

Let the distance be x km.

Then ( time taken to walk x km ) + ( time taken to ride be x km ) = hrs

⇒ ( time taken to walk 2x km ) + ( time taken to ride be 2x km )= hrs

But time taken to ride 2x km = hrs

∴ time taken to walk 2x km = hrs = hrs = 7 hrs 45 min
