Answer:

Usain Bolt

Step-by-step explanation:

  1. 1 kilometer = 1,000
  2. So, 5 kilometers = 5,000 meters

Find out their time per 1 meter:

Usain Bolt:

  1. Set up a proportion: [tex]\frac{5000}{7.5} = \frac{1}{x}[/tex]  
  2. Cross multiply, then divide: 1 × 7.5 = 7.5, 7.5 ÷ 5000 = 0.0015

The rabbit:

  1. Set up a proportion: [tex]\frac{30}{2.4} = \frac{1}{x}[/tex]  
  2. Cross multiply, then divide: 1 × 2.4 = 2.4, 2.4 ÷ 30 = 0.08

Compare the times:

  1. Usain Bolt: 0.0015 minutes in 1 meter
  2. Rabbit: 0.08 seconds in 1 meter
  3. Because 0.0015 minutes is faster than 0.08 seconds, Usain Bolt is the answer.

I hope this helps!
