Question

please...... answer that the distance between the sun and the earth is 1.6*10power of 8km .a sun ray will take 8minutes to reach the earth then find the speed of the sunray

Answer 1

distance between earth and sun = 1.6×10^8
=> 160000000

Time taken by Sun ray = 8 minutes
=> 8/60 = 2/15

speed of the Sun ray = distance/time
=> 160000000 ÷ 2/15
=> 160000000×15/2
=> 2400000000/2
=> 1200000000
=> 1.2×10^9
