Problema Solution
A fisheye lens has a minimum focus range of 13.5 centimeters. If 1 centimeter is equal in length to about 0.39 inches, what is the minimum focus range of the lens in feet.
Answer provided by our tutors
1 cm = 0.39 in
13.5 cm = 13.5*0.39 in = 5.265 in
1 ft = 12 in
1 in = 1/12 ft
5.265 in = 5.265*1/12 ft = 0.43875 ft
The minimum focus range of the lens is 0.43875 feet.
