Given the speeds of each runner below, determine who runs the fastest.

Tju [1.3M]

Answer:

Stephanie

Step-by-step explanation:

To compare each runner's speed, we must convert them all to the same units.

Let's convert then all to feet per second.

1. Stephanie

Speed = 13 ft/s

2. Emily

$\text{Speed} = \dfrac{\text{538 ft}}{\text{45 s}} = \text{12.0 ft/s}$

3. Brooke

$\text{Speed} = \dfrac{\text{1 mi}}{\text{560 s}} \times \dfrac{\text{5280 ft}}{\text{1 mi}} = \text{9.4 ft/s}$

4. Katie

$\text{ speed} = \dfrac{\text{747 ft}}{\text{1 min}} \times \dfrac{\text{1 min}}{\text{60 s}} = \textbf{12.4 ft/s}$

Stephanie is the fastest runner.
