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.

To solve this problem using a unit rate, we need to find out how many school-supply kits can be put together in one minute, and then multiply that by the number of minutes we are interested in.

To find the number of kits per minute, we need to divide the total number of kits (40) by the total number of minutes (8):
40 kits ÷ 8 minutes = 5 kits per minute

Now, we can multiply the number of kits per minute (5) by the desired number of minutes (30) to find the total number of kits that can be put together in 30 minutes:
5 kits/minute × 30 minutes = 150 kits

Therefore, at this rate, the volunteers can put together 150 school-supply kits in 30 minutes.

To solve this problem using a unit rate, we need to find the number of school-supply kits the volunteers can put together in 1 minute and then multiply that by 30 to get the number for 30 minutes.

We are given that the volunteers can put together 40 school-supply kits in 8 minutes.

To find the rate per minute, we divide the total number of kits by the total number of minutes:

40 kits ÷ 8 minutes = 5 kits per minute.

So, the volunteers can put together 5 school-supply kits in 1 minute.

To find out how many kits they could put together in 30 minutes, we simply multiply the rate per minute by the number of minutes:

5 kits per minute × 30 minutes = 150 kits.

Therefore, the volunteers could put together 150 school-supply kits in 30 minutes.

To solve this problem using a unit rate, we need to determine the rate at which the volunteers put together the school-supply kits.

We know that in 8 minutes, the volunteers put together 40 school-supply kits. This gives us a rate of 40 kits per 8 minutes.

To find out how many kits they could put together in 30 minutes, we can set up a proportion using the unit rate:

40 kits / 8 minutes = x kits / 30 minutes

To solve for x, we can use cross-multiplication:

40 kits * 30 minutes = 8 minutes * x kits

1200 kits = 8x

Then, we divide both sides of the equation by 8 to isolate x:

1200 kits / 8 = x

150 kits = x

Therefore, the volunteers could put together 150 school-supply kits in 30 minutes using a unit rate.
