Question

According to Nasa, when the International Space Station (ISS) is at an altitude of 385 kilometers, it travels at about 17,178 miles per hour. After how many hours of travel will the ISS reach a star that is 1.8 lightyears away? Recall that 1 light year = 9.5 ∙ 1012 kilometers and 1 kilometer = 0.62 miles. In your final answer, include all of your calculations.

Answer 1

Answer:

Supposing the ISS travels at a constant speed, then use the relation,

t=space/velocityt=space/velocity

Then you will obtain,

t=1.65\cdot 10^9\ hourst=1.65⋅109 hours
