Answer:
Step-by-step explanation:
The length of the train = 160 m
The length of the platform = 140 m.
The train running at a speed of 40 km/hr has to cover a distance of 160+140+160 = 460 m from the time the driver touches the platform till the guard leaves the platform.
40 km/hr = 40*1000/60 = 666.666 m/min
So the time taken by the train to pass the platform = 460/666.666 = 0.69 minutes or 41.4 sec.
