A 200 m long train is travelling at a constant speed of 20 m/s. How long will it take to completely cross a 1000 m long railway platform?
A1 minute ✓ Correct
B1.5 minutes
C2 minutes
D2.5 minutes
Correct answer: (A) 1 minute — The train takes 1 minute to cross the platform, so that is the answer.
Explanation
★The train takes 1 minute to cross the platform, so that is the answer.
★To cross the platform the train covers its own length plus the platform length.
★That is 200 plus 1000, which is 1200 m.
★The speed is 20 m/s.
★The time is 1200 divided by 20, which is 60 seconds.
★60 seconds is 1 minute.
