Let's treat the speed in one hour as a variable.

x = 120
120 mph is your answer.
The answer would be 45 weeks, since you do 530-80 since that is the part the parents will foot, which will be 450 left. Then you do that divided by 10 since you plan to save 10 dollars a week and therefore are left with 45 weeks.

-3 -3
7y=10y+6
-10y -10y
3y=6
Y=2
