You can put this solution on YOUR website! Hilary figures the horse walks about twice as fast as she does.
If her horse was hurt about 8 miles into her ride and her whole trip took 4 hours total,
how fast does Hilary walk?
:
Let s = rate of H's walk
then
2s = rate of horses walk
:
Write a time equation, time = dist/rate
:
ride time + walk time = 4 hrs + = 4
Multiply by 2s
8 + 2(8) = 4(2s)
8 + 16 = 8s
8s = 24
s = 3 mph H walks

:
Check solution by finding the times
8/6 = 1.33
8/3 = 2.67
--------------
total 4 hrs
