Question

A satellite can move at 17,000 miles per hour. How many hours will it take to reach a star that is three light years away?

Answer 1

,The star is 3 light years, or 3(9.5 • 1012) = 28.5 • 1012 = 2.85 • 1013 kilometers away

(2.85 • 1013)(0.62) = 1.767 • 1013 miles

1.767 • 1013 miles ÷ 17,000 miles/hour = 1,039,411,765 hours.
