Question

Find the unit rate for each, then compare. Which is faster?

8 laps in 70 seconds
12 laps in 98 seconds.

Answer 1

8 laps in 70 seconds is faster.

Explanation:

If we divide 70/8 and 98/12 we get the following:

70/8= 8.75

98/12=8.16

8.75>8.16

The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds
