Light travels at a speed of `3 xx 10^8 m s^(-1)`. How long does light take to reach the earth from the sun, which is `1.5 xx 10^11` m away?

Explanation

To find out how long light takes to reach the Earth from the Sun, we can use the formula:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

### Step 1: Identify the given values
- Distance from the Sun to the Earth = \( 1.5 \times 10^{11} \) meters
- Speed of light = \( 3 \times 10^{8} \) meters per second
