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!!!

(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
