Verified step by step guidance

1. Identify the relationship between minutes and hours: 1 hour = 60 minutes.
2. Set up the conversion factor to convert minutes to hours. Since you want to convert minutes to hours, use the factor \( \frac{1 \text{ hour}}{60 \text{ minutes}} \).
3. Multiply the given time in minutes by the conversion factor: \( 180 \text{ minutes} \times \frac{1 \text{ hour}}{60 \text{ minutes}} \).
4. Cancel the units of minutes to leave the result in hours: the 'minutes' units cancel out, leaving only 'hours'.
5. Perform the division of 180 by 60 to find the equivalent time in hours (do not calculate the final number here, just set up the expression).
