Question

A train passes 300 m long platform in 30secand it crosses a signal on the station in 12sec find:a) the speed of the train in km/h
​

Answer 1

${\small{\bold{\purple{\underline{Answer}}}}}$

Time difference while crossing platform and a signal is 30 - 12 = 18s.

=> Train travels 300m in 18s

=> Speed of train = 300/18 x 18/5 = 60 km/hr.

=> Length of train = 300/18 x 12 = 200m.
