To solve this question, we need to calculate the time it takes for light to travel from the Sun to the Earth, using the given dataTo solve this question, we need to calculate the time it takes for light to travel from the Sun to the Earth, using the given 

1. **Distance from Earth to the Sun**: \( 1.496 \times 10^{11} \) meters
2. **Speed of light**: \( 3 \times 10^8 \) meters per second

### Step-by-Step Solution

1. **Calculate the Time in Seconds**:
   \[
   \text{Time} = \frac{\text{Distance}}{\text{Speed}}
   \]
   Plugging in the values:
   \[
   \text{Time} = \frac{1.496 \times 10^{11}}{3 \times 10^8} = 498.67 \text{ seconds}
   \]

2. **Convert Seconds to Hours**:
   Since there are 3600 seconds in an hour:
   \[
   \text{Time in hours} = \frac{498.67}{3600} = 0.13852 \text{ hours}
   \]

3. **Round to 3 Significant Figures**:
   Rounding 0.13852 to 3 significant figures gives:
   \[
   \text{Time} \approx 0.139 \text{ hours}
   \]

Thus, the time it takes for light to travel from the Sun to Earth, correct to 3 significant figures, is **0.139 hours**.
