First and third, second can still be simplified.
(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min
At the same rate, it would take Petra 56 minutes to jog 7 miles.

70%
Step-by-step explanation:

70%

To find her hourly rate, divide the total pay by total hours worked:
130.50 / 18 = $7.25
