Question

One light year is the dist travelled by a light in one year. If the speed of light is 300000 km/s and light of the sun take 8 min to reach the surface of earth, find the dist of the sun from the earth

Answer 1

we know that
s = d/t
or, d= s × t
d= 300000× 8 × 60
d= 144,000,000 km

Answer 2

300,000 m/s multiplied by 60 (60 seconds in a minute) multiplied by 8 = 144 million km (approx.)
