To set up the equation I got:

5(x)+9(8-x)=8

5x+72-9x=8

-4x=-64

x=16

but this gives me a negative number for the walking.

WHAT IS THE CORRECT WAY TO SET UP AND SOLVE THE EQUATION?

**Damon**, Thursday, February 26, 2009 at 8:02amYou x is TIME, not distance

5(x) + 9 (1-x) = 8

5 x + 9 -9 x = 8

- 4x = - 1

x = 1/4 or 15 minutes walking

3/4 hour jogging

3/4 * 9 = 27/4 = 6.75 km jogging
