Question

The distance of Saturn from the Sun is 1.43 × 10⁹ km . If the speed of light is 3 × 10 ms-¹ , how long in seconds , does it take for the light to travel from Sun to Saturn ?​

Answer 1

4,767 seconds

Explanation:

The speed of light is actually 3x10^8 m/s, not "3 × 10 ms-¹."

Convert 1.43 × 10⁹ km = 1.43 × 10^12 m

(1.43 × 10⁹ km = 1.43 × 10^12 m)/(3x10^8 m/s) = 4,767 seconds
