7) A train 100m long is moving with a velocity of 60km/h. Find the time it takes to cross the bridge 1km long.​

Answer 1

Explanation:

Train 100m long and moving with velocity 60km/hr=60× 5/18 =>50/3 m/se

We have to find time train will take to cross a brige 1km i.e 1000m long.

Length of train be lt , length of bridge be lb and velocity of train be v

So time taken = (lt+lb)/v

= >(100+1000)/50/3

=>66sec
