Understanding the Total Time
To calculate 20% of 1 hour and 30 minutes, we first need to convert the entire duration into minutes.
- 1 hour = 60 minutes
- Therefore, 1 hour and 30 minutes = 60 minutes + 30 minutes = 90 minutes
Calculating 20% of 90 Minutes
Next, we will find out what 20% of 90 minutes is.
- To calculate 20%, you multiply by 0.20.
- So, 20% of 90 minutes = 90 minutes × 0.20 = 18 minutes
Final Answer
Thus, 20% of 1 hour and 30 minutes is 18 minutes.
- The correct answer is option 'C': 18 minutes.
This breakdown clearly shows how we arrive at the answer by first converting the time into a single unit (minutes) and then calculating the percentage from that total.
