Final answer:

It would take approximately 10 years to travel 10 light-years at the speed of light.

Step-by-step explanation:

The speed of light is approximately 300,000 kilometers per second. To calculate the distance light travels in 1 year, we can multiply the speed of light by the number of seconds per year. So:

Distance = Speed x Time

Distance = 300,000 km/s x (60 s/min x 60 min/hr x 24 hr/day x 365 days/yr)

By multiplying these values together, we find that light travels approximately 9.5 trillion kilometers in 1 year, which is equal to 1 light-year.

Therefore, if you were to travel at the speed of light, it would take approximately 10 years to travel 10 light-years.

A light year is the DISTANCE light travels through vacuum in 1 year.

If light is traveling through vacuum, then it's traveling at the speed of light in vacuum. If a student at home at the beginning of the trip is holding the clock, then ...

Traveling 1 light year takes 1 year.

Traveling 2 light years takes 2 years.

Traveling 3 light years takes 3 years.

Traveling 10 light years takes 10 years.

If the light is traveling through some other substance, or if the clock is traveling along with the light, then these numbers all change.

YOU cannot travel at the speed of light. We have to just leave it at that
