Illustration 29: The average temperature of a city from Monday to Saturday is 25 degrees Celsius. Due to sudden rainfall, the average temperature for the whole week fell to 24.5 degrees Celsius. Find the temperature on Sunday.
Answer (2)
To solve this problem, we need to find the temperature on Sunday based on the average temperatures given for the week.
Step-by-step Solution
Determine the Total Temperature for Monday to Saturday :
The average temperature from Monday to Saturday is 25°C.
There are 6 days from Monday to Saturday.
Therefore, the total temperature for these 6 days can be calculated as:
[\text{Total temperature from Monday to Saturday} = 25 \times 6 = 150
\text{ degrees Celsius}]
Determine the Total Temperature for the Whole Week :
The average temperature for the entire week is 24.5°C.
A full week consists of 7 days.
Therefore, the total temperature for the entire week is:
[\text{Total temperature for the whole week} = 24.5 \times 7 = 171.5
\text{ degrees Celsius}]
Calculate the Temperature on Sunday :
To find the temperature on Sunday, subtract the total temperature from Monday to Saturday from the total temperature for the whole week:
[\text{Temperature on Sunday} = 171.5 - 150 = 21.5
\text{ degrees Celsius}]
Therefore, the temperature on Sunday is 21.5 degrees Celsius.
The temperature on Sunday is 21.5 degrees Celsius. This was calculated using the total temperatures of Monday to Saturday and the whole week. By subtracting the total for the first six days from the total for all seven days, we found the temperature for Sunday.
