Answer :
Final answer:
Dean should set the oven to 200ºC, which is the average of the two temperatures, 170ºC and 230ºC. The average is found by adding the temperatures and dividing by two. This ensures that both recipes can cook simultaneously as close to their desired temperatures as possible.
Explanation:
Finding the Average Temperature
To determine what temperature Dean should set the oven to, we need to find the average of the two temperatures: 170ºC and 230ºC. This can be calculated using the following steps:
- Add the two temperatures together: 170 + 230 = 400.
- Divide the sum by 2 to find the halfway point: 400 / 2 = 200.
Therefore, Dean should set the oven to 200ºC, which is the temperature halfway between the two required temperatures.
