Question

Do it. 

sume that a file named People txt contains a list of names. Write a code sample
at uses a while loop to read the file and display its contents in a ListBox control.
Programming Problems
1. Distance Calculator
If you know a vehicle's speed and the amount of time it has traveled, you can calcu-
late the distance it has traveled as follows:
Distance
Speed x Time
For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is
120 miles. Create an application with a form similar to the one shown in Figure 5-51.
The user enters a vehicle's speed and the number of hours traveled into text boxes.
When the user clicks the Calculate button, the application should use a loop
to display in a list box the distance the vehicle has traveled for each hour of that
time period.
