: I need to find the speed on the side roads...I really am no good at word problems and need help...Thank you...
During rush hour, Fernando can drive 20 miles using the side roads in the same time that it takes to travel 10 miles on the freeway. If Fernando's rate on the side roads is 6 mi/h faster than his rate on the freeway, find his rate on the side roads. This question is from textbook Beginning Algebra

Rate on side road = x+6
Rate on freeway = x
Equation:

Cross multiply:
10(x+6)=20(x)
10x+60=20x
10x=60
x=6
6+6=12
Hence, his rate on the side road is 12mph.

20/(X+6)=10/X OR 10X+60=20X OR 10X=60 OR X=6 THEN X+6=12MPH
