Answer 1

To convert kilometers to meters, you can use the conversion factor that 1 kilometer is equal to 1,000 meters.

So, to convert 32 kilometers to meters, you can calculate:

\[
32 \text{ kilometers} = 32 \times 1,000 \text{ meters} = 32,000 \text{ meters}
\]

In scientific notation, 32,000 meters can be expressed as:

\[
3.2 \times 10^4 \text{ meters}
\]

Therefore, the correct answer is:

**D. 3.2 × 10^4 meters**
