The North Colony Trail at Royal Gorge, Colorado, is 18 miles long. Stacey has hiked eight miles to a resting spot. She hikes the rest of the trail at two miles per hour. When Stacey reached the sixteenth mile, how long has she been walking from the resting spot? Can someone please help I need a good grade please!

4 h

Step-by-step explanation:

The resting spot was at the 8 mi mark.

When Stacey reached the 16th mile, they had covered  

16 mi - 8 mi = 8 mi

They took 2 h for every 1 h, so

It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
