#t={y-x}/500# is the required time equation. You can find exact value, if you put the values of initial height of your's as well as your friend.

Let's say,

#x=# Inititial height of your's.
#y=# Initial height of your friend's.

After #t# minutes, the height taken out from you's initial height and added to your friends' height should be same, So

Initial Height #-# Rate of Descent #=# Initial Height #+# Rate of Ascent

#x-250(t)# #=# #y+250(t)#

Solve the equation for #t#, and you will get the time they are apart.

#500t=y-x#

#t={y-x}/500#

That's it!
