To find: How much it takes time.
The time is equal to
Given information:
A satellite camera takes a rectangle-shaped picture. The smallest region that can be photographed is a
Calculation:
The area of the original rectangle is
Assume that it takes
Since the rectangle increase at rate of
Since the area of the new rectangle is
Solve for
Ignore the negative value, so the time is
Hence, the time is
