A jogger begins her workout by jogging 7 miles to the park.
She takes an alternate route home that takes an hour longer and is a total of 14 miles.
If she jogs at the same pace what is her speed?
:
let s = the jogging speed
:
Write a time equation; time = dist/speed
14 mi time - 7 mi time = 1 hr - = 1
multiply equation by s
14 - 7 = 1s
s = 7 mph is her speed
