Remember that 1 feet is equal to 12 inches, and 1 inch is by definition equal to 2.54cm. Write 7.33km in cm. Then convert that quantity in centimeters to inches, and finally, convert that quantity in inches to feet:
[tex]7.33\operatorname{km}=7330m=733,000\operatorname{cm}[/tex]
Use the conversion factor 1in=2.54cm:
[tex]733,000\operatorname{cm}\times\frac{1in}{2.54\operatorname{cm}}=\frac{733,000}{2.54}in=288,582.7in[/tex]
Use the conversion factor 1ft=12in:
[tex]288,582.7in\times\frac{1ft}{12in}=\frac{288,582.7}{12}ft=24,048.6ft[/tex]
Therefore, the approximate value of 7.33km in feet, is:
[tex]24,000[/tex]
