C. 1 hour/ 60 minutes

D. 60 minutes/ 1 hour

Answer 1

Answer: 60 minutes/1 hour

Step-by-step explanation: took the quiz

Answer 2

The conversion ratio that student skipped was:

D. (60 minutes/1 hour)

Explanation:

We have to convert 18 hours into seconds

We know that there are 60 seconds in a minute and 60 minutes in an hour.

So, 1 hour= 60×60 seconds

18 hour= 18×60×60 seconds

In the question student converted 1 minute into 60 seconds but forgot to convert 1 hour into 60 minutes

Hence, the conversion ratio that student skipped was:

D. (60 minutes/1 hour)
