HOW TO CALCULATE AVERAGE SPEED:

  • The average speed of a moving object can be calculated by dividing the distance moved by the object by time taken. That is;

  • Average speed = distance ÷ time

  • According to this question, a bowling ball moves 18 meters every 2 seconds down the lane at a bowling alley. The average speed can be calculated as follows:

  • Average speed = 18m ÷ 2s
