Bonnie left Dallas and drove north at 40 miles per hour.
Three hours later Clyde headed north from Dallas on the same road at 70 miles per hour until he caught up with Bonnie.
How long did Bonnie drive before Clyde caught up. HOw far had she driven.
:
Both will have driven the same distance, when C catches B
:
First find out how long it will take C to catch B
Let t = travel time of C
then
(t+3) = travel time of B
:
Write distance equation; dist = speed * time
70t = 40(t+3)
:
Find t, then use that value to find the distance, the distance each traveled should be equal
