Distance between A and B is 550 km. Two trains start running towards each other with the speed of 60 km/hr and 50 km/hr respectively. Find the time taken by them to meet each other.

4 hrs 5 hrs 5.5 hrs 6 hrs

5 hrs

Relative speed in opposite direction = 60 + 50 = 110 km/hr Total Distance = 550 km Now, Time = \(\frac{Total\;distance}{Relative\;speed}\) = \(\frac{550}{110}\) = 5 hrs.
