Question

Daren can jump rope 116 times in 2 minutes, Kyle can jump rope 240 times in 4 minutes, and Marissa can jump rope 225 times in 5 minutes. Who can jump rope the most times per minute?

Answer 1

Kyle can jump rope the most times per minute.

Step by step explanation:

We have been given that Daren can jump rope 116 times in 2 minutes.

So number of rope jumps done by Daren in 1 minute will be:

`\text{Unit rate of Jump rope done by Daren}=\frac{116\text{ times}}{2\text{ minute}}`

`\text{Unit rate of Jump rope done by Daren}=58\frac{\text{ times}}{\text{ minute}}`

Therefore, Daren jumps rope 58 times per minute.

We have been given that Kyle can jump rope 240 times in 4 minutes.

So number of rope jumps done by Kyle in 1 minute will be:

`\text{Unit rate of Jump rope done by Kyle}=\frac{240\text{ times}}{4\text{ minute}}`

`\text{Unit rate of Jump rope done by Kyle}=60\frac{\text{ times}}{\text{ minute}}`

Therefore, Kyle jumps rope 60 times per minute.

We have been given that Marissa can jump rope 225 times in 5 minutes.

So number of rope jumps done by Marissa in 1 minute will be:

`\text{Unit rate of Jump rope done by Marissa}=\frac{225\text{ times}}{5\text{ minute}}`

`\text{Unit rate of Jump rope done by Marissa}=45\frac{\text{ times}}{\text{ minute}}`

Therefore, Marissa jumps rope 45 times per minute.

As Kyle jumps rope 60 times per minute, which is greater than jumps rope done by Daren and Marissa, therefore, Kyle can jump rope the most times per minute.
