Understanding the Time Calculation
To find the elapsed time between two points in the day, we can break it down into hours and minutes. In this case, we need to calculate the time from 8:15 AM to 12:45 PM.
Step 1: Calculate the Hours
- Start time: 8:15 AM
- End time: 12:45 PM
To find the number of hours between 8:15 AM and 12:45 PM:
- From 8:15 AM to 12:15 PM is 4 hours.
- Then, from 12:15 PM to 12:45 PM is an additional 30 minutes.
Step 2: Combine the Time
Now, combine the hours and minutes:
- Total time = 4 hours + 30 minutes
This gives us a total elapsed time of 4 hours and 30 minutes.
Conclusion
So, the elapsed time between 8:15 AM and 12:45 PM is:
- 4 hours 30 minutes, which corresponds to option B.
Remember, when calculating time, always break it down into manageable parts—first hours, then minutes—to avoid confusion!

Understanding Time Conversion
To calculate the total number of seconds in 5 minutes and 30 seconds, we need to convert both minutes and seconds into seconds. Here’s how you can do it.
Step 1: Convert Minutes to Seconds
- There are 60 seconds in 1 minute.
- Therefore, to convert 5 minutes into seconds:
- 5 minutes × 60 seconds/minute = 300 seconds
Step 2: Add the Remaining Seconds
- We have an additional 30 seconds to add to the conversion.
Step 3: Total Calculation
- Now, add the seconds from minutes to the additional seconds:
- 300 seconds (from 5 minutes) + 30 seconds = 330 seconds
Final Answer
- Therefore, the total time of 5 minutes and 30 seconds is 330 seconds.
This matches option B from the provided choices.
To summarize:
- 5 minutes = 300 seconds
- 30 seconds = 30 seconds
- Total = 300 + 30 = 330 seconds
So, the correct answer is option B: 330 seconds.

Understanding Temperature Conversion
When converting Celsius to Fahrenheit, we use the formula:
F = (C × 9/5) + 32
Here, F represents Fahrenheit and C represents Celsius.
Step-by-Step Calculation
1. Insert the Celsius Value
For this problem, we start with 25°C.
2. Multiply by 9/5
Calculate: 25 × 9/5
- 25 × 9 = 225
- 225 ÷ 5 = 45
3. Add 32
Now, add 32 to the result obtained in the previous step:
45 + 32 = 77
Final Result
The conversion of 25°C results in 77°F.
Answer Choices
Based on the calculation:
- a) 70°F
- b) 75°F
- c) 77°F (Correct Answer)
- d) 80°F
The correct answer is option C: 77°F.
Conclusion
Thus, when converting 25 degrees Celsius to Fahrenheit, we find that the correct answer is indeed 77°F, confirming option C as the right choice. Understanding and using the conversion formula effectively allows us to switch between Celsius and Fahrenheit with ease.

Rohini Seth answered |
To calculate the boiling point of water in Fahrenheit, we use the conversion formula from Celsius to Fahrenheit:
F=(C×9/5)+32
Where:C is the temperature in Celsius (100°C for boiling water), F is the temperature in Fahrenheit.
Step-by-Step Calculation:
1.Multiply the Celsius temperature by 9/5
100×9/5=180
2. Add 32 to the result:
180+32=212
So the answer is 212°F
So the answer is 212°F

Understanding Time Conversion
To convert hours and minutes into minutes, we need to break down the time into its components and then perform the necessary calculations.
Step 1: Convert Hours to Minutes
- 1 hour is equal to 60 minutes.
- Therefore, 2 hours can be calculated as:
- 2 hours x 60 minutes/hour = 120 minutes.
Step 2: Add Additional Minutes
- Next, we have 45 minutes to add to the previous total.
- So, we add 45 minutes to 120 minutes:
- 120 minutes + 45 minutes = 165 minutes.
Conclusion
The total time of 2 hours and 45 minutes is equivalent to 165 minutes.
Hence, the correct answer is option 'B'.
Summary of the Calculation
- 2 hours = 120 minutes
- 45 minutes = 45 minutes
- Total = 120 minutes + 45 minutes = 165 minutes
With this breakdown, it is clear why the answer is option 'B' (165 minutes). Understanding these conversions is essential in solving various time-related problems in mathematics.

Rohini Seth answered |
To convert Fahrenheit to Celsius, use the following formula:
Subtract 32 from the Fahrenheit temperature.
Multiply the result by 5/9.
For 95°F:
Subtract 32: 95 - 32 = 63
Multiply by 5/9: 63 × 5/9 = 35°C
Therefore, 95°F is equal to 35°C.
