• 25

• 4

• 30

Answer explanation

Zoee drove 300 miles/6 hours. Divide 300 by 6 to get Zoee's unit rate. 300/6 = 50 miles per hour.

Hailee drove 800 miles/10 hours. Divide 800 by 10 to get Hailee's unit rate. 800/10 = 80 miles per hour.

Then take Hailee's unit rate of 80 miles per hour and subtract Zoee's unit rate of 50 miles per hour. 80-50=30. Zoee's rate is 30 miles per hour slower than Hailee's.
