The ratio between successive speeds of a six-speed gearbox (assuming that the gears are evenly spaced to allow for whole teeth) is

where M is the maximum speed in revolutions per minute and m is the minimum speed. Write a function speedsRatio that calculates this ratio for any maximum and minimum speeds. Write a main function that prompts for maximum and minimum speeds (rpm), calls speedsRatio to calculate the ratio, and displays the results.
