To calculate the time it takes light to travel from the Sun to the Earth, we can use the formula distance (d) = speed (v) x time (t).
Given:
Speed of light (v) = 3.0 x 10^5 km/s
Distance between Sun and Earth (d) = 1.5 x 10^8 km
Rearranging the formula, we can solve for time (t):
t = d / v
Now, let's substitute the given values into the equation:
t = (1.5 x 10^8 km) / (3.0 x 10^5 km/s)
To divide these numbers in scientific notation, we need to perform the division of the coefficients and subtract the exponents:
t = 5 x 10^2 s
Therefore, it takes light approximately 500 seconds to travel from the Sun to the Earth.
