Malay walks around a circular field at the rate of 7 rounds per hour,while Neha runs around it at the rate of 11 rounds per hour. They start in the same direction from the same point at 02:45 p.m. They shall first cross each other at:

03:00 p.m.

The relative speed between Malay and Neha =  11 - 7 = 4 rounds/hour

(Because  they are in the same direction )

Time taken to  complete one round at this speed = \(\frac{1}{4}\) hour

=   \(\frac{1}{4}\) × 60 minutes

= 15 minutes

So,  First time they meet at = 2:45 + 15 min = 3:00 pm
