Question

The train is 100 M long and it takes 30 seconds to cross the 400 M bridge. What is the speed of the train?

Answer 1

The train is 100 m long

The bridge is 400m long

if the train is already 100m long

then the bridge is 300m long

Speed = distance /Time

D=300m , T=30s

s= 300/30

s=10

Speed is of 10m/s
