Answer 1

To convert miles to kilometers, Dean should be using the appropriate conversion factor, which is 1 mile ≈ 1.60934 kilometers.

Based on the potential errors listed:

1. The decimal point in his answer is in the wrong place. - This could be a valid error if Dean's conversion calculation led to an answer that is not accurate due to a misplaced decimal.

2. He has the wrong units in his answer. - If Dean provided an answer in miles instead of kilometers, this error applies.

3. Dean should have used two conversion factors. - This is generally not necessary for a simple mile-to-kilometer conversion unless he is converting from miles to another unit before converting to kilometers, which is not indicated in this scenario.

4. Dean should have kilometers in the denominator of the conversion factor. - This is incorrect because typically the conversion factor is set up such that miles are in the denominator when you want to convert to kilometers.

Based on the context provided, the two applicable errors would be:

• The decimal point in his answer is in the wrong place.
• He has the wrong units in his answer.

These errors highlight potential mistakes in the calculation and the result presented.
