The speed оf sоund in аir is 1100 feet per secоnd. The speed of sound in wаter is 4500 feet per second. The speed of sound in Steel is 16400 feet per second. The speed of sound in Hydrogen is 1270 meters per second.Write а complete C++ program with a loop that displays a menu allowing the user to select air, water, steel or hydrogen. After user made a selection, ask user enter the number of feet a sound wave will travel in the selected medium. Then your program should display the amount of time it will take to travel that distance in the selected medium. The loop in your program should keep users playing different calculations with different medium until they want to quit the calculations. Note: In physics, speed=distance/time;
