Question 1020164: As part of her training routine for basketball, Shaylle alternates between cycling and running for exercise. She cycles at a rate of 18 mph and runs at a rate of 8 mph. If she spends 9.5 hours exercising and covers a total of 131 miles, how much time did she spend on each exercise?

This is actually a problem of linear equations----Shaylie spends a total amount of time of 9.5 hours exercising. Thus:
x+y=9.5
And her miles covered is:
18x+8y=131
So:
18x+8y=131
8x+8y=76
10x=55
x=5.5
y=4
Thus she spends 5.5 hours cycling, and 4 hours running!!!!!!!!
