If A and B start moving in opposite direction at 9:30 am. After meeting they took 25 min and 4 min to reach at the starting points of each other. Find at what time they meet each other.

9:00 am 9:30 am 9:36 am 9:40 am

9:40 am

Meeting time = \(\sqrt {T_1\;×\;T_2}\)                    = \(\sqrt {25\;×\;4}\)                    = 10 min Therefore, They met each other at = 9:30 + 10min = 9:40 am
