Writing to Learn A driver averaged 30\(\mathrm { mph }\) on a 150 -mile trip and then returned over the same 150 miles at the rate of 50\(\mathrm { mph }\) . He figured that his average speed was 40\(\mathrm { mph }\) for the entire trip. (a) What was his total distance traveled? (b) What was his total time spent for the trip? (c) What was his average speed for the trip? (d) Explain the error in the driver's reasoning.

Writing to Learn In Example 2 (before rounding) we found the average temperature to be 65.17 degrees when we used the integral approximation, yet the average of the 13 discrete temperatures is only 64.69 degrees. Considering the shape of the temperature curve, explain why you would expect the average of the 13 discrete temperatures to be less than the average value of the temperature function on the entire interval.
