To calculate the temperature increase per minute, you divide the total temperature increase by the total amount of time it took for this increase to occur.
Given:
- Total temperature increase: 6 degrees Fahrenheit
- Total time: 30 minutes
Now, we perform the division to find the increase per minute:
Increase per minute = Total temperature increase ÷ Total time
Increase per minute = 6 degrees Fahrenheit ÷ 30 minutes
Increase per minute = 0.2 degrees Fahrenheit per minute
So the temperature of the liquid increased by 0.2 degrees Fahrenheit every minute.
