Suppose you start your clock at the instant the cars are 2000 feet apart. First express the velocities of the cars in feet per second. After $t$ seconds how far has the first car travelled? How far has the second car travelled? What is the sum of the distances the two cars have travelled in $t$ seconds? At what time $t$ is this sum equal to 2000 feet? I hope this helps, Penny
