2. a student on the track team runs 45 minutes each day as a part of her training. she
begins her workout by running at a constant rate of 8 miles per hour for a minutes,
then slows to a constant rate of 7.5 miles per hour for b minutes.
which equation describes the relationship between the distance she runs in miles, d,
and her running speed, in miles per hour?
a, a + b = 45
b. 8a +7.5b =d
c.0.865) +7.506) =d
d. 8(45 - b) + 7.5b = d
