Question 1201064: Using a system of equations in two variables, solve the following:
Al and Bev traveled from their apartment to a picnic 20mi away. Al traveled on his bike while Bev, who left later, took her car. Al's average rate was half of Bev's average rate. The trip took Al a half hr longer than Bev. What was Bev's average rate? Answer by josgarithmetic(39617) (Show Source):

SPEED TIME in hour DISTANCE
AL (bike) r 20/r 20
BEV (car) 2r 20/(2r) 20
DIFFERENCE
Can you understand how to solve with the displayed information?
Do you really need to use two variables instead of the one?
