Question

2.4 kilometer + 18 hectometer

Answer 1

4.2 kilometers

Explanation:

First, let's convert both values to the same unit, kilometers:

- 2.4 kilometers (already in kilometers)

- 18 hectometers can be converted to kilometers by recognizing that 1 hectometer is equal to 0.1 kilometers. So,
`\(18 \, \text{hectometers} * 0.1 \, \text{kilometers/hectometer} = 1.8 \, \text{kilometers}\)`.

Now, add the converted values:

`\[2.4 \, \text{kilometers} + 1.8 \, \text{kilometers} = 4.2 \, \text{kilometers}\]`

The sum of 2.4 kilometers and 18 hectometers is 4.2 kilometers.
