Given
Initial Temprature(At time = 0 minutes) = 40 degree Fahrenheit
Temprature after 8 minutes of heating = 80 degree Farenheit
Find
A function to determine temprature after t time
Step-by-step explanation
Rate of change of temprature = (80 - 40)/(8-0)
= (40)/8 = 5
Thus the required expression = 5m + 40
Final Answer
T = 5m+40
