How many seconds will a train 62 m in length, travelling at the rate of 45 km an hour, take to pass another train 85 m long, proceeding in the same direction at the rate of 31 km an hour?
Relative speed = 45 – 31 = 14 km/hr Speed (m/sec) = 14 × (5/18) = 35/9 m/sec Time = Total length of both the trains/Relative speed => Time = (85 + 62)/(35/9) = 37.8 sec
