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.

9:40 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
