Question

Nico can do 42 push-ups in 3 minutes.

What is the unit rate?

How many push-ups can Nico do in 5 minutes at the same rate?

Answer 1

Explanation:

Hey there!

It is said we need to find the unit rate.

What we can do is apply Unitary Method.

3 minutes = 42 push ups

1 minute =
`\sf{\bf{(42)/(3)}}`

So, 12 push ups per minute is the unit rate.

In 5 minutes, he will do 12×5 = 60 push ups!

Hope it helps :)
