Answer 1

The student likely skipped the conversion from hours to minutes. To convert hours to seconds correctly, you need to use both the conversion from hours to minutes and the conversion from minutes to seconds.

Here's the correct breakdown of the conversion:

1. Convert hours to minutes:

   • \( 18 \text{ hours} \times 60 \text{ minutes/hour} = 1080 \text{ minutes} \)

2. Convert minutes to seconds:

   • \( 1080 \text{ minutes} \times 60 \text{ seconds/minute} = 64800 \text{ seconds} \)

The conversion ratio that she skipped is: 1 hour = 60 minutes.
