Test: Time & Temperature - 2 - Class 5 MCQ

To convert 2 hours and 45 minutes into minutes, follow these steps:

120 + 45 = 165 minutes.

Therefore, 2 hours 45 minutes is equal to 165 minutes.

6:30 PM can be converted to the 24-hour clock format as follows:

To convert 250 minutes into hours and minutes, follow these steps:

Therefore, 250 minutes is equal to 4 hours and 10 minutes.

Use the conversion formula:
C = (F - 32) × 5/9

Given: F = 212
Substitute:
C = (212 - 32) × 5/9

Therefore, 212°F = 100°C

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

Use the conversion formula: F = C × 9/5 + 32.
Given: C = 25º
Compute:

Therefore, 25°C = 77°F.
Correct Option: C

The increase in temperature can be calculated simply by subtracting the initial temperature from the final temperature.

Thus, the increase in temperature is 15°C.

To find the freezing point of water in Fahrenheit, use the conversion formula from Celsius:
Formula: F = (C × 9/5) + 32

C is the temperature in Celsius (0°C for freezing water).

F is the temperature in Fahrenheit.

Step-by-Step Calculation:

 The freezing point of water in Fahrenheit is 32°F.
