W The diameter of the earth's moon is 2,159 miles. The diameter of Jupiter is 86,881 miles. a) How many of earth's moons could fit across the diameter of Jupiter? Round your answer to the nearest whole number. b) The average distance between earth and its moon is 384,400 kilometers. At their closest point (when both planets are lined up on the same side of the sun), the distance between earth and Jupiter is 588,000,000 kilometers. Using these two distances, and the fact that 1 kilometer = 0.62 miles, how much further away from earth (in miles) is Jupiter than our moon? 80°F hp ho 12 AA & 4. 08.n| bartleby ATESMZCWODQONTI2/a/MjkONjMONzQOMTY5/details M Gmail Translate : P.1 English 11/SEL. 3 Int Math III [Per. 2 J.
