shuttle for $57\mathrm{.}0$ years $($after escaping the events of the movie Alien$)$ according to a stationary observer. If Ripley only thinks she was in the shuttle $($and in suspended animation$)$ for $38\mathrm{.}1$ years, how fast was her shuttle moving?

For these, and all others with speed, feel free to work in $\backslash (\backslash$mathrm$\{$m$\}/\backslash$mathrm$\{$s$\}\backslash )$ or in terms of $\backslash ($ c $\backslash ).$ If doing the latter just put $"\backslash ($ c $\backslash )"$ as the units.
