Question

A t-shirt launcher can launch 6 shirts in 30 minutes. What is the number of shirts per hour?​

Answer 1

There are 12 shirts launched in an hour.

Explanation:

We can view this as a ratio.
`(6)/(30)` There are 60 minutes in an hour. So, let's double it.
`(12)/(60)` is our new answer. And so, we have our answer.

Answer 2

12 shirts

Explanation:

If a T-Shirt Launcher can launch 6 shirts in 30 minutes, that means it can launch 12 shirts in an hour, because there are 60 minutes in a hour, and 30 minutes is half os 60 minutes, so we just do 6 x 2 = 12.
