The following table shows the approximate speed of sound in air, water, and steel.
Write a program that displays a menu allowing the user to select air, water, or steel. After the user has made a selection, he or she should be asked to enter the distance a sound wave will travel in the selected medium. The program will then display the amount of time it will take. (Round the answer to four decimal places.) Input Validation: Check that the user has selected one of the available choices from the menu. Do not accept distances less than 0.
