Question

Calculus question. A baseball diamond is a square with side 90ft. A batter hits the ball and runs toward first base with a speed of 24ft./s.
a) At what rate is his distance from second base decreasing when he is halfway to first base?

Answer 1

Remember the distance he is from second base is \[\sqrt{90^2+(90-x)^2}\]Where \(x\) is his position from home.

Answer 2

How did you get that?
