Question

The speed of light is roughly 3.0×10^8 m/s if it takes light 8 minutes and 20 seconds to get from the sun to earth what is the distance between the sun and earth

Answer 1

First we will convert the time into seconds
1 min = 60 s
8 min = 60x8 = 480 s

480 + 20 = 500 s

Using formula d = rt
d = 3.0x10^8 x 500
d = 1.5x10^11 meters

Or 150 000 000 kilometers (150 million kilometers)
