In order to do this problem, you would have to set up rate of change equation. Distance/time (d/t)
7 mi/80 mins = x mi/64 mins
Solve this equation by solving for x.
80x = 7(64)
X = 5.6
So Tammy ran 5.6 miles.

The speed of Tammy 7:80=7/80
for 64 minutes she runs S=speed . time=7/80 x 64= 28/5= 5.6 miles
