Also calculate the distance traveled on the moon, also in meters, for a specific number of seconds. Do not include any global variables Your program must have the main function and, at least, the following four additional functions. The signatures for these functions must be as follows: double readSeconds() double calculateEarthDistance(double seconds) double calculateMoonDistance(double seconds) void displayResults(double seconds, double earthDistance, double moonDistance) The readSeconds function will be an input function that will read in a double value from cin and return that value back to main.
