If A and B start moving in opposite direction at 07.30 am. After meeting they took 45 min and 20 min to reach at the starting points of each other. Find at what time they meet each other.

08.00 am

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

                   = \(\sqrt {45\;×\;20}\)

                   = 30 min

Therefore,

They met each other at = 7 : 30 + 30 min = 8 : 00 am
