The number of minutes in 15 days is equal to the number of seconds in

Options

A. 6h
B. 8h
C. 4 h
D. 5 h

Answer

To solve the problem, we need to find out how many minutes are in 15 days and then equate that to the number of seconds in a certain number of hours.

### Step-by-Step Solution:

1. **Calculate the number of minutes in 15 days:**
- We know that there are 24 hours in a day.
- Therefore, in 15 days, the total number of hours is:
\[ 15 \text{ days} \times 24 \text{ hours/day} = 360 \text{ hours} \]
- Next, we need to convert hours into minutes. Since there are 60 minutes in an hour:
\[ 360 \text{ hours} \times 60 \text{ minutes/hour} = 21600 \text{ minutes} \]

2. **Set up the equation for seconds in hours:**
- We need to find how many hours correspond to 21600 minutes in terms of seconds.
- We know that there are 60 seconds in a minute, so the total number of seconds in \( h \) hours is:
\[ h \text{ hours} \times 60 \text{ minutes/hour} \times 60 \text{ seconds/minute} = 3600h \text{ seconds} \]

3. **Equate the two quantities:**
- Now, we set the number of minutes in 15 days equal to the number of seconds in \( h \) hours:
\[ 21600 = 3600h \]

4. **Solve for \( h \):**
- To find \( h \), divide both sides of the equation by 3600:
\[ h = \frac{21600}{3600} \]
- Simplifying this gives:
\[ h = 6 \]

### Conclusion:
The number of seconds in 6 hours is equal to the number of minutes in 15 days.
