If A and B start moving in opposite direction at 09:30 am. After meeting they took 16 min and 9 min to reach at the starting points of each other. Find at what time they meet each other.

9:42 am

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

                   = \(\sqrt {16\;×\;9}\)

                   = 12 min

Therefore,

They met each other at = 9:30 + 12 min = 9 : 42 am
