: A runner begins her workout by jogging to the park, a distance of 3 miles. She then jogs home at the same speed but along a different route. This return trip is 9 miles and he time is one hour longer. Complete the accompany chart abd use it to find the runner jogging speed. t=d\t This question is from textbook Prealgebra and Introductory Algebra
You can put this solution on YOUR website! Let the speed be x
9x-3x=(x)(x)
Factor left side:
x(x-6)=0
x=0 or x=6
hence, the jogging speed is 6mph.
