Convert speed of light to kilometers per second. You are currently converting speed units from speed of light to kilometers per second. 1 c = 299792.458 kps. speed of light. kilometers per second.
So.. 1 kilometer = 0.621371192 miles so since 186,282.397 mi. = 299.337 km per second, multiply 299.337 by 360 to get how many kilometers per hour light travels which is 107761.32 km per hour. Then, since there are 8,765.813 hours in a year, light travels a total of 944615579.75316 km per year. 50,000km/h X 8765.813 = 438290650 km per year So you're looking at roughly two years.
