9,600 school-supply kits
9,600 school-supply kits
6 school-supply kits
The correct answer is 150 school-supply kits.
To solve this problem using a unit rate, we can divide the number of school-supply kits by the number of minutes it took to assemble them.
40 kits / 8 minutes = 5 kits/minute
Then, we can multiply the unit rate by the number of minutes we want to find the number of kits for.
5 kits/minute * 30 minutes = 150 school-supply kits
Therefore, volunteers could put together 150 school-supply kits in 30 minutes.
To solve this problem using a unit rate, we can first determine the number of school-supply kits that can be put together in 1 minute.
Since volunteers can put together 40 kits in 8 minutes, the rate at which they assemble kits is 40 kits / 8 minutes = 5 kits per minute.
Next, we can use this unit rate of 5 kits per minute to find out how many kits can be assembled in 30 minutes.
30 minutes is six times longer than 5 minutes, so we multiply the unit rate by 6.
5 kits per minute * 6 minutes = 30 kits
Therefore, the volunteers can put together 30 school-supply kits in 30 minutes.
So the correct answer is 30 school-supply kits.
To solve this problem using a unit rate, we begin by finding the rate at which the volunteers can put together school-supply kits. In this case, they were able to put together 40 kits in 8 minutes.
To find the unit rate, we divide the number of kits by the number of minutes. So, the unit rate is 40 kits / 8 minutes = 5 kits per minute.
Now that we have the unit rate, we can use it to determine how many kits they could put together in 30 minutes. We multiply the unit rate (5 kits per minute) by the number of minutes (30 minutes):
5 kits/minute * 30 minutes = 150 kits
Therefore, the volunteers could put together 150 school-supply kits in 30 minutes.
