The sunling is very powerful and very long from our eyesight, that's why much time to reach the light from here.

Distance of sun from earth = 150,000,000 km
Speed of light = 3,00,000 km/sec = 18,000,000km/minute
So time taken by sunlight to reach earth = (150,000,000 / 18,000,000) minute = 8.3 min
Speed of light = 3,00,000 km/sec = 18,000,000km/minute
So time taken by sunlight to reach earth = (150,000,000 / 18,000,000) minute = 8.3 min

Speed of light = 3x10^8 m/s.
Distance between the earth & the Sun is = 150000000 KM.
So the time taken by light to cover this.
Distance is = 150000000000 m/3x10^8 m/s => 500 sec. /60 => 8 min. 20 sec.
