Question

Justin is training for a hamburger eating competition. He is eventually able to eat 15 hamburgers in 10 minutes.

What is Justin's eating rate?

A)1 hamburger per minuteB)1.5 hamburgers per minuteC)2 hamburgers per minuteD)10 hamburgers per minute

​

Answer 1

B) 1.5 hamburgers per minute

Explanation:

Justin eats hamburgers at a rate of 15 hamburgers every 10 minutes. The problem is asking you to find the unit rate, which is how many hamburgers he can eat per one minute. To find unit rate, you start with your ratio and divide:

`(hamburgers)/(minute)=(15)/(10)=(1.5)/(1)`

So, the unit rate is 1.5 hamburgers every minute or choice B.
