Rate of Change problem.
 
I am having a hard time with the start of a word problem regarding rate of change. It is pretty easy (or at least it seems)... but i can't get started with it... any help will be appreciated again!!!

Question -

A baseball diamond has the shape of a square with sides 90 feet long. A player is running from first to second base at a speed of 28 feet per second. Find the rate at which the distance from home plate is changing when the player is 30 feet away from second base...

And also- A player is running from second base to third base at a speed of 28 feet per second is 30 feet from third base. At what rate is the players distance "s" from home plate changing?

-------------------------------------------------------------------------------------

I am thinking that I have to use Pyg Ther - but i am not sure... Thank you everyone... and i am so grateful for this message board!!!

Where is home plate in relation to the diamond?

Good morning Skipjack,

Home plate is on the bottom of the diamond.


(hopefully this works)

2nd base

3rd base 1st base

Home Plate

Hopefully that helps.. because I am lost.. I looked at this again last night and was just as stumped as before :(
