Question

Four bicyclists travel different distances and times along a straight path. Which cyclist traveled with the greatest average

speed?

A

B

Cyclist 2 travels

87 min 22 s

Cyclist 4 travels

108 min 24 s

D

Cyclist 1 travels

95 m in 27 s

Cyclist 3 travels

106 m in 26 s

Answer 1

The cyclist with the greatest average speed is Cyclist 4 with average speed of 4.5 m/s

Step-by-step explanation:

Given;

Cyclist 1 travels 9 m in 27 s

Cyclist 2 travels 87 m in 22 s

Cyclist 3 travels 106 m in 26 s

Cyclist 4 travels 108 m in 24 s

Determine the average speed of the cyclists as follows;

Average speed of Cyclist 1: v = 9/27 = 0.33 m/s

Average speed of Cyclist 2: v = 87/22 = 3.96 m/s

Average speed of Cyclist 3: v = 106/26 = 4.08 m/s

Average speed of Cyclist 4: v = 108/24 = 4.5 m/s

Therefore, the cyclist with the greatest average speed is Cyclist 4 with average speed of 4.5 m/s
