Question
At its closest approach, Mercury is 77.3 million $\mathrm{km}$ from Earth. How long would it take to send a radio message from a space probe of Mercury to Earth when the planets are at this closest distance?
Step 1
We know that 1 kilometer is equal to $10^3$ meters. So, we multiply the given distance by $10^3$ to convert it to meters: \[Distance = 77.3 \times 10^6 \, km \times 10^3 \, m/km = 77.3 \times 10^9 \, m\] Show more…
