"How many miles above the earth do the polar-orbiting satellites travel?" We read that polar- orbiting satellites travel 833 km above the earth. We had to look up how many kilometers were in a mile. One kilometer equals .62 miles. We took that number and multiplied .62 times 833 and got the answer 516.46. That means that the polar-orbiting satellites travel 516.46 miles above the earth. If we got in a car and traveled from Ferrisburgh 516 miles, we would be about in Washington DC! That would take us over 8 and a half hours to get there! Grade Three Jennifer and Mary
