Hi. I need some help.(adsbygoogle = window.adsbygoogle || []).push({});

A baseball diamond is a 90 foot square. A player approaches 3rd base at a rate of 28 feet per second at the instant he is 30 feet from 3rd base. Find the rate of change of the player's distance from homeplate.

So df/dt= 28

But I don't know where to go from here.
