A 225 metres train crosses a 275 metres long tunnel in 1 minute. what is the speed of the train in km/hr ?

Answer»

LENGTH of train = 225

length of tunnel = 275

total length = 500 m


time = 1 MIN = 60 seconds


speed = d/t = 500/60 = 50/6 m/s

= 50/6 * 18/5 (multiply by 18/5 to convert it into km/h)

= 30 km/h
