Answer: There would be 48 shirts launched

To find this answer...
We need to find a unit rate

A unit rate is how many (blank) there is per (blank)
In this case, it would be how many shirts per minute

To find the unit rates all we have to do is 4÷15

4÷15= 0.26 repeated

Now, we can find how many shirts are launched per 3 hours.
We can do 60 × 3 to find the number of minutes in an hour (180)
We multiply 180 by 0.26 to find our final answer

180 × 0.26 = 48 (rounded)

Hope this helps!
