Jack drives 24 miles in 30 min. Jill drives 52 miles in 60 min. Are these equivalents rates? Why?

The rates are not equivalent. Jill's rate is higher.

Step-by-step explanation:

We can find the unit rate in miles per minute for each and compare.

Jack:

24 miles in 30 min

(24 miles) / (30 min) = 0.8 miles/min

Jill:

52 miles in 60 min

(52 miles) / (60 min) = 0.866 ... miles/min

The rates are not equivalent. Jill's rate is higher.
