Question

The average earth-sun distance is 1.50 × 10^11 m. How long does it take sunlight to reach the earth?

Answer 1

8.33 minutes

Step-by-step explanation:

Distance between Earth and Sun = 1.5×10¹¹ m

Speed of light = 3×10⁸ m/s

Time = Distance / Speed

`\text{Time taken}=(1.5* 10^(11))/(3* 10^8)\\\Rightarrow \text{Time taken}=500\ seconds`

`500\ seconds=(500)/(60)=8.33\ minutes`

∴ Time it takes for sunlight to reach the Earth is 8.33 minutes.
