Question

John and Tim start walking from the same place in the opposite directions If Tim walks at a speed of 5 5 km/hr and John at a speed of 3
km/hr, in how much time will they be 34 km apart?​

Answer 1

Step-by-step explanation:

John takes 6.8 hours

and

Tim takes 11.33 hours

Answer 2

4 hours(ANSWER)

They both start walking from the same position.

Here we will use the concept of relative velocity, to solve this problem that is

We will take one of them at rest and give his velocity to another boy.

The speed of Tim is 5.5km/hr.

The speed of John is 3km/hr.

Here we will take John at rest and give his velocity to Tim.

So, the net velocity of Tim will be 8.5km/hr.

So, the total time is taken by them to be separated by 34km=

(34km/8.5km/hr)= 4 hours (ANSWER)
