Two boats leave from the same point at the same time...help!!?

Two boats leave from the same point at the same time. One boat travels due east and the other travles due north. One boat travels 6 kilometers faster than the other. After 4 hours, the boats are 67 kilometers apart. A- Let X be the speed of the slower boat. Write a quadratic equation that models the situation. B- Use a graphing calculator to solve the equation in part a graphically. What are the solutions, to the nearest hundreth? C- What are the speeds of the boats? Round your answers to the nearest hundreth. I know this uses a triangle and pythagorean therom and all that, but i need the answers!

1. Here's a quadratic equation, but you're on your own with the graphing calculator since I don't have one. 4(x)2 + 4(x+6)2 = 4489
