Given:
The distance traveled by radio waves is d = 603.32 km
Required: The time taken to transmit the wave over this distance.
Step-by-step explanation:
The time taken to transmit the wave can be calculated by the formula

Here, c is the speed of the wave whose value is

On substituting the values, the time taken by the wave will be

Final Answer: The time taken to transmit the distance by the wave is 2011.067 microseconds.
