You drive from your home to a vacation resort 580 miles away. You return on the same highway. The average velocity on the return
trio is 5 miles per hour slower than the average velocity on the outgoing trip. Express the total time required to complete the round trip, T , as a function of the average velocity on the outgoing trip, x. T(x)=
Ooh so the directions tell us what we need to find the entire line, which is made up of FH. so just add GH (15) and FG (6) together to find FH. so that is 21. FH=21.
