A car is running at a speed of 108 kmph. What distance will it cover in 15 seconds ?

Correct answer: C. 450 metres

  • A. 45 metres
  • B. 55 metres
  • C. 450 metres
  • D. Cannot be determined

Explanation

Convert 108 km/h to metres per second: 108 x 1000/3600 = 30 m/s. In 15 s, the distance is 30 m/s x 15 s = 450 m; 45 m results from failing to multiply by the full 15 seconds.

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.
