72 hours 6 minutes `-: 14 = ?`

Options

A. 6 hours 9 minutes
B. 5 hours 9 minutes
C. 59 minutes
D. 7 hours 8 minutes

Explanation

To solve the problem of dividing 72 hours and 6 minutes by 14, we will follow these steps:

### Step 1: Convert hours into minutes
First, we need to convert the total time of 72 hours and 6 minutes into minutes. We know that:
1 hour = 60 minutes.

So, we calculate:
\[ 72 \text{ hours} = 72 \times 60 \text{ minutes} = 4320 \text{ minutes} \]

Now, we add the additional 6 minutes:
\[ 4320 \text{ minutes} + 6 \text{ minutes} = 4326 \text{ minutes} \]

### Step 2: Perform the division
Next, we divide the total minutes by 14:
\[ \frac{4326 \text{ minutes}}{14} \]

Calculating this gives:
\[ 4326 \div 14 = 309 \text{ minutes} \]

### Step 3: Convert the result back to hours and minutes
Now, we need to convert 309 minutes back into hours and minutes. We can do this by dividing 309 by 60 (since there are 60 minutes in an hour):
\[ 309 \div 60 = 5 \text{ hours} \text{ (with a remainder)} \]

Calculating the remainder:
\[ 309 - (5 \times 60) = 309 - 300 = 9 \text{ minutes} \]

### Final Answer
Thus, the result of dividing 72 hours and 6 minutes by 14 is:
\[ 5 \text{ hours} \text{ and } 9 \text{ minutes} \]

### Conclusion
The correct answer is **B. 5 hours 9 minutes**.
