Question

Ferguson and Carla began at the same time, from points 30 miles apart, to ride their bikes toward each other. They met in 2 hours. If Carla rode 3 minkes per hour faster than Ferguson, at what rate, in miles per hour, did Carla ride?

Answer 1

C (carla) = 9 miles/hour

Explanation:

F (Ferguson speed) = C (Carla) - 3

(F + C) x 2 = 30 miles

(C - 3 + C) x 2 = 30

4C - 6 = 30

4C = 36

C (carla) = 9 miles/hour
