If person A is traveling at 80% the speed of light in a vehicle with a perfect timekeeping mirror, that bounces light off the mirrors to record time very accurately, and person B was on the outside watching at the vehicle pass by, what would the time difference between the persons be to the exact decimal?

Both observers will view the others clock as running slower than their own.

At 80% of the speed of light the time dilation is obtained from the Lorentz Factor (LF), or:
LF = 1/sq rt(1-[v^2/c^2])
LF = 1/sq rt(1-[.8*186e3^2/186e3^2])
LF = 1.67 (the exact decimal is 1.6666......a repeating decimal)

In order to measure the observer's time as just one minute, it will take the other observer 1 minute and 40.2 seconds.

Note: Speed of light approximated to 186,282,397 MPS.

Hi. This site has the formula for time dilation, but the exact decimal? There would have to be something special (no pun) about 80%. : http://en.wikipedia.org/wiki/Time_dilation
