Question

A train at a speed of 45km /hr Gross station in 9 seconds Find the length of the train

Answer 1

hey first we have to convert the speed into m/sec
so..... 45km/hr = 45*(5/18) m/sec= 225/18 = 12.5 m/sec
and now...
speed= distance/ time
12.5= distance / 9
distance = 12.5×9
distance = 112.5 m
SO LENGTH OF TRAIN = 112.5 m

HOPE THIS HELP YOU ☺☺
