{
// Declare Variable
int selection;
// Prompt user to make a selection of medium between air, water or steel.
cout<<"Make Selection"<<'\n'<<"Press 1 for Air"<<'\n'<<"Press 2 for Water"<<'\n'<<"Press 3 for Steel";
cin>>selection;
// Check for entry
if(selection == 1) {
cout<<"You selected Air"<<'\n';
cout<<"The distance travelled by sound wave in air is 1,125 feet in 1 second";
}
else if(selection == 2) {
cout<<"You selected Water"<<'\n';
cout<<"The distance travelled by sound wave in water is 4859 feet in 1 second";
}
else if(selection == 3) {

}
The answer would be B. An increase in the price of a complement.
Answer:
1.152 GB if it will be at 128 kbps quality
Explanation:
So, let's say you choose your mp3 be 128 kbps (kilobits per second).
One byte is 8 bits. So 128 kbps = 16 kilobytes per second.
There is 60*60 seconds in one hour. So 16*60*60 = 57.6 megabytes per hour
Multiply by 20 hours to get your answer: 57.6*20 = 1152 MB = 1.152 GB.
The best assumption to make is that there is a hidden partition and the drive needs to be further searched.
