I have a twin brother, and we're 30 years old. If i travel for three years at 2.55 X 10^8m/s (0.85c) while my brother is a rest on Earth, how much older than me will my brother be upon my return?

2. Relevant equations

t=To/√1-v^2/c^2

3. Try to work out

To=3

T=?

V= 2.55 X 10^8 m/s

C= (.85c) 2.55 X 10^8 m/s

T= 3/ (all of this under a square root sign -->)1-(2.55 x 10^8)^2/(2.55 x 10^8)^2

t=3/0

*i get stuck here because you cant have a zero in the denominator*
