Homework Help: calculus

Posted by Anonymous on Monday, March 30, 2009 at 12:20pm.

Could someone help me et up this problem?

Two people start from the same point. one walks east at 3mi/h and the other walks northeast at 2mi/h. How fast is the distance between the poeple changing after 15 minutes?

I think this is what I would do:::

First I would set up a triangle:

hypotenuse=h (northeast walking person)
height=y
leg=x (north walking person)

GIVEN: dx/dt=3mi/h
dh/dt=2mi/h

Need to find dy/dt when t=15.
