Answer: The average rate of change of temperature from 0 to 1.5 hours after the storm began is -3.445 degrees F per hour. The average temperature during the first 1.5 hours of the storm was 75.834 degrees F.To calculate the average rate of change of temperature, we need to find the change in temperature during the first 1.5 hours, which is the integral of the rate of change of temperature from 0 to 1.5. Thus,Average rate of change = (1/1.5) * ∫[0,1.5] t(h)dh= (1/1.5) * [2.34 - 8.64 + 13.3775 - 9.99]= -3.445 degrees F per hourTo calculate the average temperature during the first 1.5 hours, we need to find the average value of the temperature from 0 to 1.5 hours. Thus,Average temperature = (1/1.5) * ∫[0,1.5] [80 + t(h)] dh= (1/1.5) * [120 + 3.9 - 6.48 + 7.62 - 4.995]= 75.834 degrees FTherefore, The average temperature during the first 1.5 hours of the storm was 75.834 degrees F.
