To find the temperature at which the Celsius and Fahrenheit scales will show the same reading, we can use the conversion formula between the two scales:
°C = (°F - 32) * 5/9
We need to find a temperature at which both the Celsius and Fahrenheit values are equal. Let's assume the temperature is x.
So, x = (x - 32) * 5/9
Simplifying the equation, we get:
9x = 5x - 160
4x = -160
x = -40
Therefore, the temperature at which the Celsius and Fahrenheit scales will show the same reading is -40 degrees.
Answer: D. - Minus 40 degrees.

Time taken by sunlight to reach the Earth:
- The speed of light in a vacuum is approximately 299,792 kilometers per second.
- The distance from the Sun to the Earth is about 149.6 million kilometers.
- To calculate the time taken by sunlight to reach the Earth, we divide the distance by the speed of light.
Calculation:
- Distance from the Sun to the Earth: 149.6 million kilometers
- Speed of light: 299,792 kilometers per second
- Time taken = Distance / Speed

- Time taken = 149,600,000 km / 299,792 km/s
- Time taken = 498.65 seconds
Converting seconds to minutes:
- 1 minute = 60 seconds
- Time taken = 498.65 seconds / 60 seconds/minute
- Time taken ≈ 8.31 minutes
Therefore, sunlight takes approximately 8 minutes to reach the Earth.
