Question

A train 270 metres long is running at a speed of 36 km per hour,then it will cross a bridge of length 180 metres in

Answer 1

Answer:

0.05 sec

Step-by-step explanation:

length =270m

speed=36km/h

speed in m/s=36*5/18=10m/s

bridge length =180 m

speed=distance/time

10 =180/time

10/180=time

time=1/18

time=0.05 sec.

Answer 2

Step-by-step explanation:

length = 270 m

speed = 36 km /hr

speed in m/s = 36×5/18 = 10 m /a

bridge length = 180 m

speed = distance / time 10 = 180/T

T = 10/180

=1/18

Therefore time = 0.5 sec
