If A and B start moving in opposite direction at 11:30 pm. After meeting they took 25 min and 9 min to reach at the starting points of each other. Find at what time they meet each other.

11:45 pm

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

                   = \(\sqrt {25\;×\;9}\)

                   = 15 min

Therefore,

They met each other at = 11:30 pm + 15 min = 11 : 45 pm
