Question
How many seconds will a train 64 m in length, travelling
at the rate of 42 km an hour, take to pass another train 82 m long, proceeding in the same direction at the rate of 30 km an hour?Solution
Relative speed = 42 – 30 = 12 km/hr Speed (m/sec) = 12 × (5/18) = 10/3 m/sec Time = Total length of both the trains/Relative speed => Time = (82 + 64)/(10/3) = 43.8 sec
