Seema walks around a circular field at the rate of 3 rounds per hour, while Priya runs around it at the rate of 8 rounds per hour. They start in the same direction from the same point at 11:54 p.m. When will they first cross each other?

Question

Accepted Answer

Seema's speed = 3 rounds/hour
Priya's speed = 8 rounds/hour

Since both start at the same point and move in the same direction, the time taken for Priya to catch up with Seema (i.e., to cross each other) is when the relative distance covered by Priya equals 1 round.

Relative speed = (8 - 3) rounds/hour = 5 rounds/hour

Time to meet = Distance / Relative speed = 1 round / 5 rounds per hour = 1/5 hour = 12 minutes

They start at 11:54 p.m., so they will first cross each other at 11:54 p.m. + 12 minutes = 12:06 a.m.
