Quizplus · Accepted Answer

The distance light travels in a given time can be calculated using the formula $d = ct$, where $d$ is the distance, $c$ is the speed of light ($3.0 \times 10^8 \, \text{m/s}$), and $t$ is the time ($2.0 \, \text{ms} = 2.0 \times 10^{-3} \, \text{s}$). Plugging in the values, $d = 3.0 \times 10^8 \, \text{m/s} \times 2.0 \times 10^{-3} \, \text{s} = 6.0 \times 10^5 \, \text{m}$.
