You need to use the velocity addition formula: http://en.wikipedia.org/wiki/Velocity-addition_formula#Special_theory_of_relativity

 

Their relative speed would be about 99.999999995% the speed of light. I'll leave it to you to plug that into the Lorentz equation... (it is about 10,000, I think).

 

My question was about the time dilation effects on each object approaching each other at say your 9.9999999995 c ?
