Question

I need to know the temperature at 4:00 pm on Tuesday and 9:00 am on wednesday

Answer 1

The temperature from noon on Tuesday until 10 am on Wednesday is:

                           

Temperature = 75^o - (2 degrees per hour)*(Hours since noon Tuesday) 

                       

Tuesday at 4pm is 4 hours past noon, so:

 

Temperature = 75^o - 2*4

Temperature = 75^o - 8^o

Temperature = 67^o

 

9 am Wednesday is 9 hours since noon Tuesday, so:

 

Temperature = 75^o - 2*9
