70 Computer Programming Concepts and Visual Basic number of kilometers and meters. The number of centimeters should be displayed to one decimal place. Some of the needed formulas are as follows: total inches = 63360 * miles + 36 * yards + 12 * feet + inches total meters = total inches / 39.37 kilometers = Int(meters / 1000) FIGURE 2-34 Sample Run for Programming Project 6
