arithmetic - p walks around a circular field at the rate of 1 round per hour while q runs around it at the rate of 5 rounds per hour they start in the same direction from the same point at 910 am they shall first cross each other at - skillgun

Solution: Since P and Q move in the same direction along the circle, so they will first meet each other when there is a difference of one round between the two
Relative speed of P and Q = (5 - 1) = 4 rounds per hour.
Time taken to complete one round at this speed = 1/4 hr = 15 min.
.'. 9.10 A.M. + 15 minutes = 9.25 A.M.
