Question

230 meters long train runs with a speed of 45 kmph. How much time train will take to pass 145 meters long platform?
1. 30 sec
2. 25 sec
3. 20 sec
4. 40 sec

Answer 1

Correct Answer - Option 1 : 30 sec

Given:

Length of train = 230 m

Speed of train = 45 km/hr = 45 × (5/18) m/s = 12.5 m/s

Length of platform = 145 m

Formula used:

Time = Distance/Speed

Calculation:

Total length covered = (230 + 145) m

⇒ 375 m

Time taken = (375/12.5) seconds

⇒ 30 seconds

∴ The time taken to cross the platform is 30 seconds
