If A and B start moving in opposite direction at 10:30 am. After meeting they took 12 min and 3 min to reach at the starting points of each other. Find at what time they meet each other.

10:36 am

Meeting time = \(\sqrt {T_1\;×\;T_2}\)

                   = \(\sqrt {12\;×\;3}\)

                   = 6 min

Therefore,

They met each other at = 10:30 + 6min = 10:36 am
