The tortoise and the hare finally have a rematch. The tortoise gets a 1000 ft lead and runs 1.5 feet per second. The hare begins at the starting line and runs at a rate of 6 feet per second. There is also a rat in this race. The rat starts 1200 ft ahead of the hare and runs back towards the starting line in the opposite direction at a rate of 3 feet per second. Let x represent time in seconds and y represent the distance in feet.

Write an equation for each of the runners.
