the temperature of town A at 4 pm was 41 degrees above zero. The temperature recorded at10 pm was 29 degree C. If the temperature falls at a constant rate per hour, find the fall in temperature per hour. Please Explain!
difference of the temprature = 41-29 = 12
difference of the time = 10 pm - 4pm = 6 hours
temperature fall at a constant rate per hour ,so fall temperature per hour is = 12/6 = 2'C per hour
