To find the number of school-supply kits that can be put together in 30 minutes, we can set up a proportion using the unit rate.
The unit rate is the number of kits put together per minute, which is found by dividing the total number of kits (40) by the time (8 minutes).
Unit rate = 40 kits / 8 minutes = 5 kits/minute
Now, we can set up a proportion to find the number of kits in 30 minutes:
5 kits/minute = x kits/30 minutes
Cross-multiplying, we get:
5x = 150
Dividing both sides by 5, we find:
x = 30
Therefore, volunteers can put together 30 school-supply kits in 30 minutes.
