Question
Mars is roughly 60 million $\mathrm{km}$ from earth. How long does it take for a radio signal originating from earth to reach Mars? Radio signals travel at the speed of light, $186,000 \mathrm{mi} / \mathrm{s}$.
Step 1
We know that 1 kilometer is approximately equal to 0.621371 miles. So, we have: 60,000,000 km * 0.621371 mi/km = 37,282,260 miles Now, we can use the speed of light (in miles per second) to find out how long it takes for a radio signal to travel this distance. Show more…
