To find the unit rate, we divide the number of school-supply kits by the time it took to put them together.
Unit rate = (Number of school-supply kits) / (Time in minutes)
So, the unit rate is 40 kits / 8 minutes = 5 kits/minute.
To find how many kits can be put together in 30 minutes, we multiply the unit rate by the time.
Number of kits in 30 minutes = (Unit rate) * (Time in minutes) = 5 kits/minute * 30 minutes = 150 school-supply kits.
Therefore, they could put together 150 school-supply kits in 30 minutes.
To solve this problem using a unit rate, we need to find out how many school-supply kits can be put together in 1 minute.
Since volunteers can put together 40 school-supply kits in 8 minutes, the unit rate is 40 kits / 8 minutes = 5 kits/minute.
Therefore, in 30 minutes, the volunteers can put together 5 kits/minute * 30 minutes = 150 school-supply kits.
So the correct answer is 150 school-supply kits.
To solve this problem using a unit rate, we can find the number of school-supply kits put together per minute and then multiply it by the number of minutes given.
We know that volunteers put together 40 school-supply kits in 8 minutes.
Therefore, the unit rate is 40 kits / 8 minutes = 5 kits per minute.
To find the number of school-supply kits that can be put together in 30 minutes, we multiply the unit rate by the number of minutes:
5 kits/minute * 30 minutes = 150 school-supply kits
So, the correct answer is 150 school-supply kits.
