A baseball player hits a baseball from home base towards second base with a velocity of 90 feet/second. At that same moment, he runs from home base towards first base at 30 feet/second. Find the rate of change of the distance between him and the baseball after 1 second.

1. so, how do you figure the distance? Look up the various measurements of a ball field.

Then just take the derivatives and plug in your numbers.
