how fast is each car traveling?

Question

Two cars start off 800 miles apart. They begin driving towards one another, with one car going 20 miles per hour faster than the other. If it takes 4 hours for the two cars to meet, how fast is each car traveling?

Answer 1

I don't think they will ever meet...because they will both wind up in traffic court for speeding!

Remember distance = rate * time

4r + 4(r + 20) = 800

8r = 720

r = 90 and r + 20 = 110
