A radar used to detect the presence of aircraft receives a pulse that has reflected off an object $6 \times 10^{-5}$ s after it was transmitted. What is the distance from the radar station to the reflecting object?

in number 13. I'm given that the time for radar to reflect back off something is six times 10 to the negative fifth seconds. And I'm asked to find how far away that object is. Well, electromagnetic waves traveled a constant speed. Someone used my constant speed equation. Vehicles do routine. Um, so I can see my distance would just be Just rearrange that equation the distance of the equal velocity times the time Oh, electromagnetic waves go the same speed report Oh, times 10 to the eighth. I'm giving my time and I get the distance is 18,000 meters. But for radar, that's the distance to get there and back. So you can tell that is this is twice the distance, So the distance that the object is away will be 9000 meters or nine kilometers.
