Question

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?

Answer 1

To answer the question presented above, the conversion factor for km to feet is 1 kilometers is equal to 3280.84 feet. From the given,
                         (12 km) x (3280.84 ft / 1 km) = 39370.08 feet
Thus, Joe traveled an approximate distance of 39370 feet. 

Answer 2

1 km = 3280.84 feet.
One can get the conversion factor from kilometer to feet from the above deduction. To answer the second part of this question, the above conversion is definitely needed,
12 kilometers = 3280.84 x 12 feet
                       = 39370.08 feet.
So from the above deduction, it can be concluded that Joe traveled for a distance of 39370 feet.
