Question

A train 300 metres long train crosses a railway bridge of 150 metres in 30 seconds. What is the speed of the train? ​

Answer 1

Answer:

Speed of the train is 9 metres per second.

Step-by-step explanation :

Step 1 : Calculate the total distance :

Total distance

→ Length of the train + length of the bridge.

→ 300metres + 150metres.

→ 450 metres.

Step 2 : Find the speed of the train :

We know that,

Speed = Distance ÷ time

• Time taken to cross the train is 30secs. (given)

So,

→ Speed = 450 ÷ 30

→ 9m/sec.

The speed of the train is 9m/s

Answer 2

Question:
