A tortoise and a hare were competing in a foot race. Because the hare knew he could run faster than his friend, he let the tortoise have a 15-meter head start. The system {y=15+3xy=5x can be used to model the race (x is the time, in seconds, since the race began, and y is the distance, in meters, from the starting line)

Use your graph from the previous question to tell when & where the hare passed the tortoise to take the lead in the race.
