[QUOTE="MartinButler88, post: 4501306, member: 486032"] [b]Question between friends! -- How long to travel 1 light year?[/b] [h2]Homework Statement [/h2] Me and a few friends were trying to work out how long it would take a human to travel one light year. We were using the these variables. Distance = 9.4605284 × 10[SUP]15[/SUP] m Fastest speed for manned space travel = 39,846 kph or 11068.3 m/s [h2]Homework Equations[/h2] I was using the equation of speed = distance/time, rearranged to solve for time. T = D/S [h2]The Attempt at a Solution[/h2] My attempt brought me back the answer of 27084 years. I was doing this. [U]9.46 x 10[SUP]15[/SUP][/U] =854716299241 seconds or 27084 years 11068 m/s If there is any other variables I have left out, could you please write back. Me and my friends have used different speeds, different units and our heads are now fried! Thank you [/QUOTE]
