Two trucks are traveling on the same highway. The first truck travels at an average rate of 50 mi/h. The second truck leaves two hours later and travels at an average rate of 60 mi/h. How long will the trucks have traveled when the second truck catches up with the first truck?

A vehicle traveling at 50 mph travels 100 miles in two hours. In three hours it has traveled 150 miles and the second truck has traveled 60. At four hours it has traveled 200 miles, the second 120. At five hours it has traveled 250, the second 180. At six, 300 and 240 and so on. So this could be done by brute force, but let's try to think smarter, not harder.
A simpler way to solve the problem is to cancel out the equivalents. We can consider the first vehicle to be stopped and the second to be going 10 miles per hour. Since the first vehicle has 100 miles on the second, it will take ten hours plus the amount of time the first has been traveling, or twelve hours.

Sorry, but I don't do homework (not since I graduated College in 1985). Try some other forum; maybe you'll get lucky and find someone who doesn't mind doing someone else's homework. Good luck!
