km.- There are 8760 hours in a year.We will use the formula:
Now, let's plug in the values:
Calculating this, we get:
Using a calculator, we find:
However, we need to express the answer to 3 significant figures. Therefore, we round the answer to 3 s.f.:
**【Answer】:** The Earth travels approximately
km in one hour, to 3 significant figures.
