In the example provided by the US DoE in its final rule, an electric car with an energy consumption of 265 Watt hour per mile in urban driving, and 220 Watt hour per mile in highway driving, results in a petroleum-equivalent fuel economy of 335.24 miles per gallon, based on a driving schedule factor of 55 percent urban, and 45 percent highway ...
The radar mile is a unit of time (in the same way that the light year is a unit of distance), equal to the time required for a radar pulse to travel a distance of two miles (one mile each way). Thus, the radar statute mile is 10.8 μs and the radar nautical mile is 12.4 μs.
An increase of $0.15 on a price of $2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is a 6% increase. While many percentage values are between 0 and 100, there is no mathematical restriction and percentages may take on other values. [4]
In 2020, previous results are confirmed for the year 2019: mean car speed was reduced between 2.9 and 3.9 km/h, while mean speed of trucks was reduced by 2 km/h without speed limit change. By the same time, fatalities were reduce by 125 in the second semester 2018, by 84 in the first semester 2019, and 127 for the second semester 2019. [127]
Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.
A 68 kg (150 lb) person walking at 4 km/h (2.5 mph) requires approximately 210 kilocalories (880 kJ) of food energy per hour, which is equivalent to 4.55 km/MJ. [15] 1 US gal (3.8 L) of petrol contains about 114,000 British thermal units (120 MJ) [52] of energy, so this is approximately equivalent to 360 miles per US gallon (0.65 L/100 km).
55 miles per hour (89 km/h) speed limit sign being erected in response to the National Maximum Speed Limit. The National Maximum Speed Limit (NMSL) was a provision of the federal government of the United States 1974 Emergency Highway Energy Conservation Act that effectively prohibited speed limits higher than 55 miles per hour (89 km/h). The ...
Within "business or residential" districts, exceeding the speed limit by more than 20 miles per hour (32 km/h) is considered criminal. Within "urbanized areas", 55 miles per hour (89 km/h) speed limit citations are given for "waste of a finite resource". This exception only applies within a 10-mile-per-hour (16 km/h) threshold.
