A light year is the distance light travels in 1.00 year. Given the velocity of light, 1.86x10^5 m/s, how many miles does light travel in a light year?
just convert (btw i think you meant miles/s) 1.86 * 10^5 miles/second * 60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year = 1.86x10^5 miles/s * (60*60*24*365) s / year = 1.86x10^5 miles * 54864000 year = 5,865,696,000,000 miles/year thats alot
If you are asking how many miles are in a light year, the answer is 5.87849981x10^12. However, to ask how many miles does light travel in a light year is incorrect: A light year is a measure of distance, not time. So light does not travel in a light year. You should also be careful with your units: m/s denotes meters per second however you meant miles per second, right?
