1. A light-year is how astronomers measure distance in space. It’s defined by how far a beam of light travels in one year. It is mostly used to express distances to stars and other distances on a galactic scale, especially in non-specialist and popular science publications. A light second is approximately 186,000 miles/second. How far is one light year?
Solution:
formula: light second * 1 minute * 1 hour * 1 day * 1 year
186 000 miles/second * 60 seconds/minutes * 60 minutes/hour * 24 hours/day * 365 days/year = 5 865 696 000 000 miles/year

Solution:
formula: light second * 1 minute * 1 hour * 1 day * 1 year
186 000 miles/second * 60 seconds/minutes * 60 minutes/hour * 24 hours/day * 365 days/year = 5 865 696 000 000 miles/year
