Question

A 180 m long train crosses a man standing on the platform in 6 seconds. What is the speed of the train?

• A. 90 km/h
• B. 108 km/h
• C. 120 km/h
• D. 88 km/h

Answer 1

The Correct Option is B

To find the speed of the train, we start by using the formula for speed:

Speed = Distance / Time

We have:

• Distance = 180 meters
• Time = 6 seconds

Substitute the values into the formula:

Speed = 180 m / 6 s = 30 m/s

Now, to convert the speed from meters per second to kilometers per hour:

1 m/s = 3.6 km/h

Therefore, 30 m/s = 30 × 3.6 km/h = 108 km/h

Thus, the speed of the train is 108 km/h.
