Consider the following problem:
Two cars are stopped at either end of a 100km highway. At the same time, they both start driving towards each other. Car A travels at 20km/hr and car B travels at 30km/hr. At the same time as the cars start, a dog jumps out of Car A and runs towards car B at 50km/hr. When the dog reaches car B, he immediately turns around and runs back to car A. He repeats this until the cars collide.
If the dog stops running as soon as the cars meet, how far has he run?
Use the equation: speed = distance/time.
