Answer 2

Answer:

Thus the first bus takes 40 minutes to travel RS.

We've already seen that the first bus can travel PR in 3 hours. So the bus can travel PS, or it can reach S, in 3 hours 40 minutes.

This implies the first bus, which started its journey from P at 6:00, travels PS after, or reaches S at 6:00 + 3:40 = 9:40.

Hence the time at which both the buses cross each other is 9:40.
