Question

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

hello friend...!!!

we should calculate the total time taken by the train to cross the 1 km bridge .

⇒ S = 1 km + 100 m ( bridge + train length )

⇒ S = 1000 + 100 = 1100 m 

velocity = 60 km / hr = 60 x 1000 / 3600 m/s 

velocity = 16 . 6 m / s 

according to the general formula of velocity , we know ,

velocity = distance / time taken 

time taken = distance / velocity 

time =  1100 / 16.6

time = 66.2 seconds.
