Answer 2

Answer:

Explanation:

Driving at an acceptable speed limit is safer and increases the fuel economy. As for highway driving, over 50% of the power produced by the engine is used to overcome aerodynamic drag. For this reason, fuel consumption increases rapidly at speeds above 90km/h. ... Driving at a moderate speed increases fuel efficiency.

Driving in a higher gear than necessary can also improve fuel economy, as long as the engine isn't struggling. When slowing down, there's no need to change down the gears in sequence- brake until you reach your desired speed, and then select the correct gear.
