    Help with calc 1 problem: rate of change.

    I need help with this problem. Could someone show me how to get the correct answer. I get a wrong answer every time.

    A point P is moving along the curve whose equation is y=√x. Suppose that x is increasing
    at the rate of 40 units/s when x=3. How fast is the distance between p and the point (2,0) changing\
    at that instant?

    Please show your work.

    Thanks so much

    how about you show us what you've done? what is the distance between P and (2,0)?
