Question

A radio announcer's voice is transmitted via radio waves a distance of 715.18 km. How much time, in microseconds, will it take to transmit the wave over this distance?

Answer 1

We know that a radio wave travels at the speed of light and we also know that the time can be calculated by the equation:

`t=(d)/(v)`

Plugging the speed of light and the distance the wave traveled we have:

`\begin{gathered} t=(715.18*10^3)/(3*10^8) \\ t=2383.93*10^(-6) \end{gathered}`

Therefore, it takes 2383.93 microseconds to travel this distance
