**helper**, Monday, February 7, 2011 at 7:05pmD = RT (Distance = Rate x Time)

R = rate of bike

0.67 = time of bike (2/3 = 0.67)

0.67R = distance of bike

R + 12 = rate of car

0.33 = time of ca (1/3 = 0.33)

.33(R + 12) = distance of car

Since distance is equal

0.67R = 0.33(R + 12)

Solve for R, rate of bike
