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!
