D. The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to reach Saturn from Earth. Show your work. Convert your answer into scientific notation if necessary.
the distance between earth and Saturn is 1.2 billion km(746 miles) so if 28,000= 1 hr then 1,200,000,000÷28,000 is 42857.14286 or 42,857.14 (1,785.71 days. or 4.89 years)
