Kim jogged up a hill at 4 mph and then jogged back down at 8 mph.
How many miles did she travel in all, if her total jogging time was 4 hour 30 min?
:
Let d = the one-way distance
:
Write a time equation; time = dist/speed
Time up + time down = 4.5 hrs
+ = 4.5
Mult by 8, results:
2d + d = 8(4.5)
3d = 36
d = 36/3
d = 12 mi
then
2(12) = 24 mi traveled in all
