If you want to determine the time it would take to travel a distance of 4.5 light-years, we can use the fact that light travels at a speed of approximately 9.461 trillion kilometers (5.878 trillion miles) per year.
Distance = Speed x Time
Time = Distance / Speed
Plugging in the values:
Time = (4.5 light-years) / (9.461 trillion kilometers per year)
Converting light-years to kilometers:
1 light-year ≈ 9.461 trillion kilometers
Time = (4.5 x 9.461 trillion kilometers) / (9.461 trillion kilometers per year)
Simplifying the equation:
Time ≈ 4.5 years
Therefore, it would take approximately 4.5 years to travel a distance of 4.5 light-years at the speed of light.
