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

Which kind of control structure would best describe the code? Ensure that you select the answer which also includes a correct explanation. a. Sequence, because the program involves input/output. b. Selection, because control flow can take one of multiple possible paths based on a condition. c. Selection, because input is selected from the user. d.
