How many seconds will a train 60 m in length, travelling at the rate of 40 km an hour, take to pass another train 90 m long, proceeding in the same direction at the rate of 28 km an hour?
Relative speed = 40 – 28 = 12 km/hr Speed (m/sec) = 12 × (5/18) = 10/3 m/sec Time = Total length of both the trains/Relative speed => Time = (90 + 60)/(10/3) = 45 sec
