Wolfram Mathematica solving a particular equation

I'm using Wolfram Mathematica 8 and I want to make it solve this equation for the variable t: enter image description here

It probably involves using variables with longer names and having subscripts

I have tried to type your equation in Mathematica 8 and it was solved.

Here the input (in FullForm)

Solve[(Subscript[x, 2] + Subscript[Speed, Subscript[x, 2]]*t - 
  Subscript[x, 1] - 
  Subscript[Speed, Subscript[x, 1]]*t)^2 + (Subscript[y, 2] + 
  Subscript[Speed, Subscript[y, 2]]*t - Subscript[y, 1] - 
  Subscript[Speed, Subscript[y, 1]]*t)^2 == (Subscript[r, 1] + 
 Subscript[r, 2])^2, t]

Here is the result (as an image because the FullForm is too long to be informative)

Result of Solve with subscripts

Hope this example will help you find what went wrong in your case.
