Question

Quizplus · Accepted Answer

To find the time it takes for light to travel from the sun to Mars, divide the distance by the speed of light: $2.29 \times 10^{11} \, \text{m} \div 3.00 \times 10^{8} \, \text{m/sec} = 7.63 \times 10^{2} \, \text{sec}$, which is approximately $7.6 \times 10^{2} \, \text{sec}$.
