Question

a train 100 m long is moving with velocity of 60 km per hour find the time it takes to cross the bridge 1km long.​

Answer 1

Answer:

we should calculate the total time taken by the train to cross the 1 km bridge . time = 66.2 seconds.

Explanation:

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
