In a line graph showing the temperature over a week, if the temperature increased from 20°C to 30°C over three days, what was the average daily increase? (2023)
2°C
3°C
5°C
10°C
The total increase is 10°C over 3 days, so the average daily increase is 10/3 = 3.33°C, which rounds to 3°C.

Q
Q: In a line graph showing the temperature over a week, if the temperature increased from 20°C to 30°C over three days, what was the average daily increase? (2023)
Solution: The total increase is 10°C over 3 days, so the average daily increase is 10/3 = 3.33°C, which rounds to 3°C.
Steps: 6
Step 1: Identify the starting temperature, which is 20°C.
Step 2: Identify the ending temperature, which is 30°C.
Step 3: Calculate the total increase in temperature by subtracting the starting temperature from the ending temperature: 30°C - 20°C = 10°C.
Step 4: Count the number of days over which this increase happened, which is 3 days.
Step 5: Calculate the average daily increase by dividing the total increase by the number of days: 10°C / 3 days = 3.33°C.
Step 6: Round the average daily increase to the nearest whole number, which is 3°C.
