Question

For this question, you are required to use switch statement and dialog boxes for input and output.

Decis 12. The Speed of Sound The folowing table shows the approximate speed of sound in air, water, and steel: Medium Speed 1,100 feet per second 4,900 feet per second 16,400 feet per second Air Water Steel 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 = Distancel1,100 You can calculate the amount of time it takes sound to travel in water with the following formula: Time = Distancel4,900 You can calculate the amount of time it takes sound to travel in steel with the following formula: Time = Distancel16,400
