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

They put together 40 kits in 8 minutes, so the unit rate is:

40 kits / 8 minutes = 5 kits/minute

To find out how many kits they can put together in 30 minutes, we can use the unit rate:

5 kits/minute * 30 minutes = 150 kits

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

The correct answer is 150 school-supply kits.

To solve this problem, we can use a unit rate.

Brian can read 80 pages in 2 hours.

To find out how many pages he can read in 1 hour, we divide the total number of pages by the total number of hours:

80 pages / 2 hours = 40 pages/hour

Now, we can use this unit rate to find out how many pages Brian can read in 3.5 hours:

40 pages/hour * 3.5 hours = 140 pages

Therefore, Brian can read 140 pages in 3.5 hours.

The correct answer is 140 pages.

To solve this problem, we can use a unit rate.

In 10 seconds, the surface of the earth at the equator has moved 4,600 meters.

To find out how far the surface has moved in 1 second, we divide the total distance by the total time:

4,600 meters / 10 seconds = 460 meters/second

Now, we can use this unit rate to find out how far the surface has moved in 150 seconds:

460 meters/second * 150 seconds = 69,000 meters

Therefore, the surface of the earth at the equator has moved 69,000 meters in 150 seconds.

The correct answer is 69,000 meters.

To solve this problem, we can use a unit rate.

Grace ran a 26-mile marathon in 4 hours.

To find out how far she ran in 1 hour, we divide the total distance by the total time:

26 miles / 4 hours = 6.5 miles/hour

Now, we can use this unit rate to find out how far Grace ran in 1.5 hours:

6.5 miles/hour * 1.5 hours = 9.75 miles

Therefore, Grace ran 9.75 miles in 1.5 hours.

The correct answer is 9.75 miles.

To solve this problem, we can use a unit rate.

In 5 hours, the Acela Express traveled 775 miles.

To find out how far it traveled in 1 hour, we divide the total distance by the total time:

775 miles / 5 hours = 155 miles/hour

Now, we can use this unit rate to find out how far the Acela Express traveled in 8 hours:

155 miles/hour * 8 hours = 1240 miles

Therefore, the Acela Express traveled 1240 miles in 8 hours.

The correct answer is 1240 miles.
