Two trains are moving in the opposite directions on parallel tracks at the speeds of 64 kmph and 96 kmph respectively. The first train passes a tree in 5 seconds whereas the second train passes the tree in 6 secs. Find the time taken by the trains to cross eachother completely?

Length of train with 64Km/hr = 5 * 64 / 3.6
Length of Train with 96 Kn/hr = 6 * 96/ 3.6

Sum of their length = (5*64+6*96)/3.6

Effective speed = (64+96)/3.6 m/sec

Time = (64*5+6*96)/(64+96) = (320+576)/(160) = 5.6 seconds

I hope I am correct.
