Question

A train takes 9 seconds to cross a pole. If the speed of the train is 48 km/hr ,then length of the train is

Answer 1

The length of the train is 48000×9=432000m,i.e.,432km.

As we know,
Distance=Speed×Time
here the speed of the train is 48kmph
so we convert it into metre as the time is given in second.
so,48km×1000=48000m(1km=1000m)
Time=9seconds.
Therefore,
Distance=48000×9
=432000m,i.e.,432km. (1000m=1km)
