He can make 220 burgers in 30 minutes
Correct answer 3
He can make 120 burgers in 30 minutes

Answer 1

He can make 120 burgers in 30 minutes

Explanation:

Set up a proportion where x is the number of hamburgers he'll make in 30 minutes:

`(4)/(1)` =
`(x)/(30)`

Cross multiply:

x = 120

So, he can make 120 burgers in 30 minutes.
