The fuel economy (in miles per gallon) of a certain car is E(x) = −0.01x2 + 0.54x +10.4, where x is the driving speed (in miles per hour, 20 ≤ x ≤ 60). At what speed is fuel economy greatest? x = mph
An individual wanted to determine the relation that might exist between speed and miles per gallon of an automobile. Let X be the average speed of a car on the highway measured in miles per hour and let Y represent the miles per gallon of the automobile. The following data is collected: X 50 55 55 60 60 62 65 65 Y 28 26 25 22 20 20 17 15 a. In the space below, draw a scatterplot of the...

The corporate average fuel economy (CAFE) standard for mileage is currently 26.5 miles per gallon of gasoline (the defender) for passenger cars. To conserve fuel and reduce air pollution, suppose the u.s Congress sets the CAFE standard at 35 miles per gallon(the challenger) in 2010. An auto will emit on average 0.8 pounds of carbon dioxide(c02) per mile driven at 26.5 miles per gallon, and will emit 0.65 pounds of CO2 per mile driven at 35 miles per gallon. A....
A certain car has a fuel efficiency of 36.4 miles per gallon (mi/gal). Express this efficiency in kilometers per liter (km
Your car gets 25 miles per gallon (mpg at 60 miles per hour (mph) and 18 mpg at 70 mph At what speed should you make a 600-mile trip: a. If gas costs $3 per gallon and your time is worth S12 per hour? b. If gas costs S4 per gallon and your time is worth $15 per hour? allon and your time is worth S10 per hour? d. Build a spreadsheet to calculate the total trip cost for gas...
Suppose the car (van, SUV) you drive gets 25 miles/gallon. If you drive 19,000 miles per year how many tons of the green house gas CO2 are you releasing each year? Assume your fuel is octane (C8H18) and the combustion reaction is balanced: C8H18 + 12.5 O2 → 8 CO2 + 9 H2O Addition information: Density of octane = 0.700 g/mL 1 gallon = 3785 mL 1 pound = 454 g 1 ton = 2000 lbs
ADDITIONAL PROBLEMS Question 1.1a: A car is traveling with a speed of 55.0 miles per hour (mi/h) What is the car's speed in meters per second (m/s)? 24.59 m/s
ASAP The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55 mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55, you lose 2% in fuel economy. For example, if your automobile gets 30 miles per gallon at 55 mph, the fuel consumption is 21 miles per gallon at 70 mph. If you take a 400-mile trip and your average...
with 17 and 18 ALGEBRA1-Alternate Exam 12-continued Student's Name Student Number On a 1287 mile long road trip in windy conditions, a family calculates their fuel economy to be 18 miles per gallon over the 2 days it takes to reach their destination. On their 2-day return trip, with a similar wind at their backs, their calculations show a fuel economy of 26 miles per gallon. 17. Calculate the expected fuel economy of their vehicle in ideal (non-windy) conditions ()...
