Question

The chart below describes the speed of four runners. Which runner is the fastest?

Runner A ran 1 mile in 8 minutes

Runner B ran 2 miles in 10 minutes

Runner C ran 3 miles in 20 minutes

Runner D ran 5 miles in 30 minutes

Answer 1

Runner B

Explanation:

speed = distance ÷ time

Runner A: 1 ÷ 8 = 0.125m/ms

Runner B: 2 ÷ 10 = 0.2m/ms

Runner C: 3 ÷ 20 = 0.15m/ms

Runner D: 5 ÷ 30 = 0.17m/ms

Runner B has the highest speed so he is the fastest runner.
