Test: Time & Temperature - 1 - Class 5 MCQ

To convert 500 seconds into minutes:

• Divide 500 by 60 to find the number of whole minutes.
• 500 ÷ 60 = 8 minutes with a remainder.
• The remainder is 500 - (8 × 60) = 20 seconds.

Therefore, 500 seconds equals 8 minutes and 20 seconds.

The class starts at 9:15 AM.

It lasts for 2 hours and 45 minutes.

Add 2 hours to 9:15 AM to get 11:15 AM.

Then, add 45 minutes to 11:15 AM.

This results in a final time of 12:00 PM.

To find out how many seconds are in 5 hours, follow these steps:

• There are 60 minutes in an hour.
• Each minute has 60 seconds.

Now, calculate the total:

• 5 hours × 60 minutes/hour = 300 minutes
• 300 minutes × 60 seconds/minute = 18,000 seconds

Therefore, 5 hours is equal to 18,000 seconds.

The movie starts at 2:30 PM and ends at 5:15 PM.

Calculate the total duration:

From 2:30 PM to 5:00 PM is 2 hours 30 minutes.

Add another 15 minutes to reach 5:15 PM.

Total duration: 2 hours 45 minutes.

The initial temperature at 8:00 AM is 12°C.

The temperature rises by 5 degrees by noon.

Calculate the new temperature: 12°C + 5°C = 17°C.

The new temperature is 17°C.

The normal body temperature is 98.6°F, which needs to be converted to Celsius.

The formula for conversion is: (°F - 32) × 5/9 = °C.

Applying the conversion: (98.6 - 32) × 5/9.

This calculates to approximately 37.0°C.

Therefore, the converted temperature is 37.0°C.

The temperature dropped by:

Initial temperature: 25°C

Final temperature: 10°C

Difference:15°C drop

Using the conversion formula C = (F - 32) × 5/9
(68 - 32) × 5/9 ≈ 20°C.

Let’s add up all the times:
First event: 45 minutes
Second event: 1 hour 15 minutes is the same as 75 minutes (because 1 hour = 60 minutes + 15 minutes)
Third event: 35 minutes
Now, add these times together: 45 minutes + 75 minutes + 35 minutes = 155 minutes. Since 60 minutes make 1 hour, 155 minutes is 2 hours (120 minutes) and 35 minutes left over. So, the total is 2 hours and 35 minutes.
