Answer 1

Step-by-step explanation:

I found a more logical and fast way for me.

5h is approximately the time needed for B to do PQ.

In 5h A arrived at (3*5 km), so A is impossible.

E is impossible too because of 22>21 and in this option, B would not have returned to meet A.

Now they differ from each other just 6 km (from 15 km to 21 km). in 1 more hour, A will be at 18 km and B 21-4= 17km.

So they should have met between 17 and 18 km.

Answer C, IMO.
