Three minutes is equal to how many twentieths of an hour?

Explanation:
This question tests converting minutes to a fraction of an hour. Since one hour has 60 minutes, a given number of minutes is that many over 60 of an hour. For three minutes, that’s 3/60, which simplifies to 1/20. A twentieth of an hour is 1/20, and its decimal form is 0.05. So three minutes equals one twentieth of an hour, i.e., 0.05 hours.
