  • A fast moving vehicle takes a shorter time to reach its destination.
  • A slower moving vehicle will take a longer time to travel the same distance.

  • This measurement is called speed.
  • What is speed ? Speed involves distance and time.
  • If  we know the distance travelled and  the time taken, speed can be calculated using the formula  : speed = distance/ time
