**Question between friends! -- How long to travel 1 light year?**

## Homework Statement

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

^{15}m

Fastest speed for manned space travel = 39,846 kph or 11068.3 m/s

## Homework Equations

I was using the equation of speed = distance/time, rearranged to solve for time. T = D/S

## The Attempt at a Solution

My attempt brought me back the answer of 27084 years.

I was doing this.

__9.46 x 10__=854716299241 seconds or 27084 years

^{15}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
