as part of her training routine for basketball, shaylle alternates between cycling and running for exercise. she cycles at a rate of 14 mph and runs at a rate of 8 mph. if she spends 8.5 hours exercising and covers a total of 101 miles, how much time did she spend on each exercise?

1 answer

If she spends x hours cycling, the rest (8.5-x) is spent running. Since distance = time * speed,

14x + 8(8.5-x) = 101

Now just solve for x and figure 8.5-x
