Question

60 metre long train moving on a straight level track passes a pole in 5 seconds find the speed of the train and the time it will take to cross a 540 metre long Bridge

Answer 1

Answer:

Step-by-step explanation:

Given:

Length of the train  ( D ) = 60 m

, Time taken to cross the pole  ( T ) = 5 s

Length of the bridge  = 540 m

Speed of the train = D /T = 60 /5

Speed of the train = 12 m s − 1

Now, distance to be covered to cross a 540 m long bridge =

Length of the train + Length of the bridge = 60 + 540 = 600 m

Hence,

Time taken = distance /speed

Time taken = 600 /12  =  50 s

Answer 2

Answer:

60 meter long train moving on a straight level track passes a pole in 5 seconds find the speed of the train and the time it will take to cross a 540 meter long Bridge.

Step-by-step explanation:

In the question give that there is a train which is moving in the straight level track. The length of the train is 60 meter. It passes the pole in 5 sec. So we have to find the speed of the train and also the time the train will take to cross 540 meter long bridge.

Given:

Length of the train  ( D ) = 60 m

Time taken to cross the pole  ( T ) = 5 sec

Length of the bridge  = 540 m

• Formula of speed is speed is equal to the ratio of distance and time.

Speed of the train = $\frac{D}{T} =\frac{60}{5}$

Speed of the train = 12 m s − 1

Now, distance to be covered to cross a 540 m long bridge =

Length of the train + Length of the bridge = 60 + 540 = 600 m

Hence,

• Time taken = distance /speed

Time taken = 600 /12  =  50 s

Hence, the time taken by the train is 50 seconds.
