This is the problem:

Quinn is running aruond the circular track x^2 + y^2 = 10,000, whose radius is 100 meters, at 4 meters per second. Quinn starts at the point (100,0) and runs in the counterclockwise direction. After 30 minutes of running, what are Quinn's coordinates?

Okay first off, please don't flat out give me the answer cuz I want to do it myself. But I really just don't get how to do it!! So can someone please explain this to me?

Okay, so one, how do I draw the x^2 + y^2 = 10,000? Is it just a regular circle, the center at the origin, with an 100 meter radius?

And two, how do I find Quinn's coordinates on the graph? Once I get the circle set up, I'll be able to calculate his distance around the circle I'm sure, but how do I find the exact coordinates?

THANK YOU SO MUCH, if someone could answer within an hour or two I would be really appreciative, it is pretty urgent
