Question

A train 200m long is running with a speed of 72km/hr. ln what time will it pass a platform 160 m long?

Answer 1

Answer:18 sec

Step-by-step explanation:

Speed of a train=72km/hr

Length of train=200m or 0.2km

Length of platform=160m or 0.16km

Distance cover by tain to pass a platform=train length+ platform length

=0.2km+0.16km=0.36km

Time taken to cross a platform = distance/ speed

=0.36/72=0.005hr or 18 sec

Answer 2

It will take 0.005 hour to pass a platform 160 m long

Step-by-step explanation:

Length of train = 200 m

Length of platform = 160 m

Total distance = 200+160= 360 m

1000 m = 1 km

360 m = 0.36 km

Speed = 72 km /hour

$Time = \frac{Distance}{Speed}$

$Time = \frac{0.36}{72}$

Time =0.005  hour

Hence It will take 0.005 hour to pass a platform 160 m long
