SSC CHSL Time, Speed and Distance question with solution
Time, Speed and DistanceModerateSSC CHSL 2024
A train 500 m long is running at 90 km/h. How much time will it take to cross a pole?
- (A)17 seconds
- (B)40 seconds
- (C)24 seconds
- (D)20 seconds
Correct answer: (D) 20 seconds
Convert the speed to metres per second: 90 × 5/18 = 25 m/s. To cross a pole the train covers its own length, so time = 500 ÷ 25 = 20 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
