Answer
1.5 miles / hour
Step-by-step explanation
She jogged 2.5 miles in the first 20 minutes
Speed = distance/time
2.5 miles / 20 minutes = 0.125 miles / minute
Convert to hours
0.125 • 60 (60 minutes in an hour) = 7.5 miles / hour
She jogged 2 miles (6.8 - 4.8) in the last 20 minutes
2 miles / 20 minutes = 0.1 miles / minute
Convert to hours
0.1 • 60 = 6 miles / hour
7.5 miles / hour - 6 miles / hour
= 1.5
You just have to multiply $8.50 by 1.065.
So, the answer is 9.0525 or about $9.05
