12. The Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel:
Medium Speed
Air 1,100 feet per second
Water 4,900 feet per second
Steel 16,400 feet per second
Write a program that asks the user to enter “air”, “water”, or “steel”, and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take.
You can calculate the amount of time it takes sound to travel in air with the following formula:
Time = Distance / 1,100
You can calculate the amount of time it takes sound to travel in water with the following formula:
Time = Distance / 4,900
You can calculate the amount of time it takes sound to travel in steel with the following formula:
Time = Distance / 16,400
