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. (Assume both planets are aligned with the sun and are on the same side of the sun.) Show your work. Convert your answer into scientific notation if necessary.
(short answer)
To estimate the time it will take for the space shuttle to reach Saturn from Earth, we need to know the distance between the two planets.
The average distance from Earth to Saturn is about 1.5 billion kilometers.
Time = Distance / Speed
Time = 1.5 billion km / 28,000 km/h
Time = 53,571.43 hours
Converting to scientific notation,
Time = 5.3571 x 10^4 hours.
