Question

The table shows the number of brake pads produced in 3 hours is 48, 6 hours is 96, 9 hours is 144, and 12 hours is 192.

What is the unit rate for brake pads produced per hour?

A.

B.
3 brake pads per hour

C.
12 brake pads per hour

D.
16 brake pads per hour

Answer 1

To find the unit rate for brake pads produced per hour, we divide the total number of brake pads produced by the number of hours.

For 3 hours: 48 brake pads / 3 hours = 16 brake pads per hour
For 6 hours: 96 brake pads / 6 hours = 16 brake pads per hour
For 9 hours: 144 brake pads / 9 hours = 16 brake pads per hour
For 12 hours: 192 brake pads / 12 hours = 16 brake pads per hour

Therefore, the unit rate for brake pads produced per hour is 16 brake pads per hour.

The answer is D. 16 brake pads per hour.
