Question 1159660: The distance between two points A and B on Earth is measured along a circle having center C at the center of Earth and radius equal to the distance from C to the surface (see the figure). Assume the diameter of Earth is approximately 8,000 miles. If angle ACB has measure 1', then the distance between A and B is a nautical mile. Approximate the number of land (statute) miles in a nautical mile. (Round your answer to two decimal places.)
HELP!! I do not even know what to do Xd

.

Start calculating the circumference of the Earth, using the given diameter.

Then divide the found circumference by 360 degrees to get the length of a one degree arc.

Then divide it by 60 to get the length of a one angular minute arc.

It will be your answer.
