Cole ran 3 miles in 27 minutes . Carson ran 2 miles in 20 minutes. Aaravind ran 5 miles in 35 minutes if each student ran at a constant rate , who is the fastest runner?

Question

Roman Alvarez · Accepted Answer

Aaravind is the fastest runner.

To calculate their running speed, divide miles by minutes. Cole: #3 -: 27 = 0.bar11# Cole runs 3 miles every 27 minutes. This is equivalent to 0.11 miles per 1 minute . Carson: #2 -: 20 = 0.1# Carson runs 2 miles every 20 minutes. This is equivalent to 0.1 miles per 1 minute . Aaravind: #5 -: 35 = 0.142..# Aaravind runs 5 miles every 35 minutes. This is equivalent to 0.14 miles per 1 minute . #0.1 < 0.11 < 0.14# Aaravind runs the most miles per minute, so he is the fastest.

Riley Anderson · Answer

undefined To determine the fastest runner, we calculate the speed of each runner by dividing the distance covered by the time taken.

For Cole: Speed = $ \frac{3 \text{ miles}}{27 \text{ minutes}} $
For Carson: Speed = $ \frac{2 \text{ miles}}{20 \text{ minutes}} $
For Aaravind: Speed = $ \frac{5 \text{ miles}}{35 \text{ minutes}} $

We then compare the speeds to identify the fastest runner.
