rate = 1° / 30 min = 2° / 60 min = 2° / h
T = temperature
t = time
Temperature = rate ∙ time
T = rate ∙ t
20 ° = 2° / h ∙ t
t = 20 ° / ( 2° / h )
t = 20 ° ∙ h / 2°
t = 10 h
Reference time = 6:00 am
6:00 am + 10 h = 16 h = 4:00 pm
The temperature is shown at 6:00am. It is rising at one degree every thirty minutes. At this rate, it will be 20 degrees at what time?
