Question 97046: Someone please help me with this word problem. I am not sure what I am supposed to do to solve it.
During rush hour, Fernando can drive 40 miles using the side roads in the same time that it takes to travel 30 miles on the freeway. If Fernando's rate on the side roads is 7 mi/h faster than his rate on the freeway, find his rate on the side roads.

let s=(side road rate), so (30/40)s or (3/4)s is the freeway rate

s=(3/4)s+7 ... (1/4)s=7 ... s=28
