Question

A 300 m long train is moving at a speed of 60 km/h. In what time will it cross a single pole?

• A. 25 sec
• B. 30 sec
• C. 18 sec
• D. 12 sec

Answer 1

The Correct Option is C

The problem requires calculating the time taken by a train to cross a single pole. The formula to calculate time when distance and speed are given is:

Time = Distance / Speed

Given:

• Length of train (Distance) = 300 m
• Speed of train = 60 km/h

First, convert the speed from km/h to m/s:
1 km/h = (1000 m)/(3600 s) = 5/18 m/s
Therefore, 60 km/h = 60 × (5/18) m/s = 50/3 m/s

Calculate the time using the formula:

Time = 300 / (50/3) = 300 × (3/50) = 18 seconds

Thus, the train will cross the pole in 18 seconds.
