yes light does take time to travel, and the time taken is at the speed of light. And so depending on the distance, we will know how much time it has taken.
The definition of distance is a measurement from point A to point B. As an element of travel, the time taken to go from point A to point B is the time of travel, or the time taken to cover the distance at a certain speed.
Average speed = Distance covered/Time taken
10 years
Distance to travel divided by average speed = amount of time taken. Time now plus time taken = ETA
The answer depends on 0.28 WHAT! It should be obvious that the time taken to travel 0.28 inches will be somewhat different to the time taken for 0.28 light years!
velocity
12 hrs
15 SECONDS
Dividing distance by velocity gives the time taken to cover that distance. This is known as the time taken to travel a certain distance at a particular speed.
About 81/3 minutes
velocity = distance travelled/time taken to travel that distance
