Question

If a photon of Light leaves the sun than reachers the earth 494 second later. What is the distance from the earth to sun

Answer 1

Speed of light = 3 x 10⁸ m/s

Time to make the trip = 494 sec

Distance = (speed) x (time)

Distance = (3 x 10⁸ m/s) x (494 s)

Distance = 1,482 x 10⁸ meters

Distance = 1.482 x 10¹¹  meters

Distance = 1.482 x 10⁸  kilometers

Answer 2

The distance from the Earth to the Sun is 92.96 million mi.
