2462 mi, the distance between Los Angeles and New York.

How do we calculate how fast light travels?

I don't think you or I have the equipment to calculate the speed of light. It is 3E8 m/s
Convert 2462 mi to meters then
3E8 m/s x # sec = 2462 converted to m.
The conversion factor is 1 mile = 1609.34 meters.
It's asking for it in nanoseconds is there a change in the formula?
No. You calculate the time in seconds and convert to ns.
1O^9 ns = 1 s
