Question

a train 100 m long is running at the speed of 30 km/hr. find the time taken by it to pass a man standing near the railway line.

Answer 1

The distance is 100 m

Speed is 30 km / h

Convert this to m /s

30 × 5/18 = 8. 333 m/s

Time = Distance / speed

Time = 100 / 8.333 = 12.00s

12 seconds.
