Question

A satellite 200 miles above the earth is orbiting the earth once every 6 hours. How long, in hours, does it take the satellite to travel 8,400 miles? (Assume the radius of the earth is 4,000 miles.) Give your answer both as an exact value and an approximation to three significant digits.
Work out please

Answer 1

Find the diameter of the earth. Then divide that measurement by the number of hours it takes for the satellite to go around the earth. divide that number by the number of your "8400" miles

Answer 2
