Volunteers put together 40 school-supply kits in 8 minutes. At this rate, how many could they put together in 30 minutes? Solve this problem using a unit rate. show your work
A 10.67 school-supply kits
B 150 school-supply kits
C 9,600 school-supply kits
D 6 school-supply kits
To find the unit rate, we divide the total number of school-supply kits by the time it took to put them together:
40 kits / 8 minutes = 5 kits/minute
So, the volunteers can put together 5 school-supply kits in one minute.
To find how many kits they can put together in 30 minutes, we multiply the unit rate by the number of minutes:
5 kits/minute * 30 minutes = 150 kits
Therefore, the volunteers can put together 150 school-supply kits in 30 minutes.
The answer is B) 150 school-supply kits.
