This could mean only that it takes that length of time for light to travel the diameter of the earth’orbit.This distance was known to be nearly 186000000miles.Siiiince it took light about 10000 seconds [nearly 17 minutes] to go this distance, it meant that the speed of light is about 186000 miles/seconds.
