Time for radio signal to get to a receiver

[Jess_18033152]

Homework Statement

A radio transmitter is located 17.5 km away. The broadcast signals travel at the speed of light (c = 3.00 x 108 m.s-1) through the air towards a radio receiver.

Calculate the time it takes the radio signal to travel from the transmitter to the receiver.

Homework Equations

Not sure on what equation to use in this case?

Thinking;
t = d/c ?

The Attempt at a Solution

t = d/c
= 17500m / (3.00 x 10^8)
= 5.83 x 10^5 s

Not sure whether this is the correct equation to use for this question, if not which equation should I use. From my notes in class I don't have an equation that uses these symbols other than t = d/c

This is roughly 7 days. Does it make sense to you that light takes a week to travel a distance of 17.5 km?

Let me also generally say that looking for an equation in notes is not a good way of learning physics. This is particularly true if you are just looking for an equation that ”uses my symbols”. You will learn much better if you try to understand why the equations are what they are. Also, symbols are just notation and there is no guarantee that another text will use the same ones. Meaning is everything.

Sorry the answer was 5.83 x 10^-5 s hahah :), thank you.
