**TL;DR Summary:**find how fast the distance is changing from 3rd base to a runer going to first base

**Mentor note**: Thread has been moved from a technical math section, so is missing the homework template.

A baseball diamond is a square with side 90 feet. A batter hits the ball and runs

toward first base with a speed of 28 feet per second.

\item [a] At what rate is his distance from second base decreasing when he is halfway to first base?

Draw a picture of the baseball diamond. The baseball player hits from home base and runs counterclockwise

towards first base. Then the player can continue counterclockwise to reach second

base, followed by third base.

so s^2=90^2+x^2
