Answer
$\Delta x=2.2\times 10^{11}m$
Work Step by Step
The velocity formula is equal to $$v=\frac{\Delta x}{\Delta t}$$ Therefore, distance is equal to $$\Delta x=v\Delta t$$ Convert 12 minutes to seconds using dimensional analysis. $$12min \times \frac{60s}{1min}=720s$$ Substituting known values of $\Delta t=720s$ and $v=c=3.00\times 10^8m/s$ yields a distance of $$\Delta x=(3.00\times 10^8m/s)(720s)$$ $$=2.2\times 10^{11}m$$
