How do I convert minutes to hours for this calculator?

Divide minutes by 60. Example: 90 minutes = 90/60 = 1.5 hours. A result of 1.5 hours = 1 hour 30 minutes.

What is average speed?

Average speed = Total Distance ÷ Total Time. It averages out periods of different speeds over the entire journey.

What is the speed of light?

The speed of light in a vacuum is approximately 299,792 km/s (or 1,079,252,848 km/h). Nothing with mass can travel this fast according to Einstein's theory of relativity.
