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.

Question

A: 150 school-supply kits
B: 6 school-supply kits
C: 9,600 school-supply kits
D: 10.67 school-supply kits

Answer 1

To find the unit rate, we divide the number of school-supply kits by the number of minutes it takes to put them together.

Unit rate = 40 school-supply kits / 8 minutes = 5 school-supply kits per minute

To find how many kits they can put together in 30 minutes, we multiply the unit rate by the number of minutes.

Number of kits in 30 minutes = 5 school-supply kits/minute * 30 minutes = 150 school-supply kits

Therefore, the answer is A: 150 school-supply kits.
