How do you write the sentence Our school needs a heating system One that is more fuel-efficient than the current system properly?
A fuel efficient SUV is probably better- not only does saving fuel save the Earth, it also helps you save money. On the other hand, standard SUVs may be cheaper, and making fuel efficient vehicles can sometimes use more energy than normal vehicles. In the end, it's still probably better to go fuel-efficient.
Why does driving slower save fuel or is more fuel efficient compared to driving faster to the same distance Isn't fastspeed n lesstime equal d same amt of fuelusage compared to slow speed n more time?
Driving faster uses more fuel for two reasons. First your engine is running at higher revolutions per minute, which uses more fuel. Second your car is encountering more air resistance the faster you go, which means your engine has to work harder and consume more fuel. Typically vehicles are most fuel efficient when well maintained and traveling at 45MPH, anything beyond that and air resistance multiplies exponentially.
