Question

1) A 150 m long train crosses a platform in 15 sec. What is the length of the platform if the speed of the train is 90km/hr.
​

Answer 1

Answer:

225m

Step-by-step explanation:

Let length of plat form be L

Total distance travelled= L+150m

Speed of train=90km/hr=25m/s

Time taken=15 seconds

Solution:

Total distance travelled by train=speed×t

= 25×15

= 375m

L+ 150= 375

L. =225m

Answer 2

Answer:

_________________

Given:

length of train-150m

Time-15sec

Speed -90km/hr-25m/s

Let the length of platform be x

Then ,total length be x+150

Distance= speed*time

X+150=25*15

x+150=375

x=375-150

=225m

Length of platform is 225m.
