How much time does a train 125 metres long running at 60 km/hr take to pass a pole?

Correct answer: C. 7.5s

  • A. 6s
  • B. 2.08s
  • C. 7.5s
  • D. 8s

Explanation

Convert 60 km/h to metres per second: 60 x 1000/3600 = 16.67 m/s. Passing a pole requires covering the train's length, so time = 125 m / 16.67 m/s = 7.5 s. The common wrong choice is 2.08 s, which results from using 60 directly with metres without converting the speed.

About Time, Speed and Distance

Problems relate distance, speed and time through the formula distance = speed × time, including unit conversion, average speed, relative speed and motion in opposite or the same direction. Questions may involve trains, boats and streams, where the effective speed changes, so average speed must not be confused with the simple average of two speeds.
