An automobile computer gives a digital readout of fuel consumption in gallons per hous. During a trip, a passenger recorded the fuel consumption every 5 minutes for a full hour of travel.

time: 0 / gal/h: 2.5
time: 5 / gal/h: 2.4
time: 10 / gal/h: 2.3
time: 15 / gal/h: 2.4
time: 20 / gal/h: 2.4
time: 25 / gal/h: 2.5
time: 30 / gal/h: 2.6
time: 35 / gal/h: 2.5
time: 40 / gal/h: 2.4
time: 45 / gal/h: 2.3
time: 50 / gal/h: 2.4
time: 55 / gal/h: 2.4
time: 60 / gal/h: 2.3

(a) Use the Trapezoidal Rule to approximate the total fuel consumption during the hour.
(b) If the automobile covered 60 miles in the hour, what was its fuel efficiency (in miles per gallon) for that portion of that trip.

Answer: (a) 2.42 gal (b)24.83mpg
