Write a function that prints how long it takes a signal from Voyager 1 to reach the Earth. Since Voyager 1 is constantly moving away from Earth, the function should have a parameter for Voyager’s current distance from Earth, in kilometers. The Voyager 1 communicates with radio waves, which travel at the speed of light, 299,792,458 m/s.
Example
The function call:
voyager(20884657351.0);Would produce the output:
It takes 69663.7 seconds for a message from Voyager to reach Earth.
