Try This 2-1 How Far Away Is the Lightning?

Sound.jeva

In this project you will create a program that computes how far away, in feet, a listener is from a lightning strike. Sound travels approximately 1,100 feet per second through air. Thus, knowing the interval between the time you see a lightning bolt and the time the sound reaches you enables you to compute the distance to the lightning. For this project, assume that the time interval is 7.2 seconds.

1. Create a new file called Sound.java.

2. To compute the distance, you will need to use floating-point values. Why? Because the time interval, 7.2, has a fractional component. Although it would be permissible to use a value of type float, we will use double in the example.

3. To compute the distance, ...
