Question

A 90 metre Long Train runs at the speed of 72km/h it croses a bridge in 10 seconds then the length of bridge is?

Answer 1

Hey mate!!!!

Here's your answer!!!

Given:

Speed = 72 km/hr

Convert it in m/s

$\frac{72*1000}{3600} => 20 m/s$

Time = 10s

As we know:

Distance = Speed * Time

Putting the values, we get:

D = 20m/s * 10s

Distance = 200m

But we're already given that the length of the train is 90 metre. Thus,

Distance = 200 - 90

Distance = 110m

Hope it helps!!!
