In other words, going between periods of efficient acceleration and gliding gives an overall efficiency that is usually higher than when cruising at a constant speed. Computer calculations have predicted that in rare cases (at low speeds where the torque required for cruising at steady speed is low) it's possible to double (or even triple) fuel ...

This is around 1 ⁄ 5 (20%) of what is needed to power a standard upright bicycle without aerodynamic cladding at same speed, and 1 ⁄ 50 (2%) of that which is consumed by an average fossil fuel or electric car (the velomobile efficiency corresponds to 4700 miles per US gallon, 2000 km/L, or 0.05 L/100 km).

The number of deaths per passenger-mile on commercial airlines in the United States between 2000 and 2010 was about 0.2 deaths per 10 billion passenger-miles. [3] [4] For driving, the rate was 150 per 10 billion vehicle-miles: 750 times higher per mile than for flying in a commercial airplane. For a person who drives a million miles in a ...
Along with numerals, and special-purpose words like some, any, much, more, every, and all, they are quantifiers. Quantifiers are a kind of determiner and occur in many constructions with other determiners, like articles: e.g., two dozen or more than a score. Scientific non-numerical quantities are represented as SI units.
The once treacherous 50-mile (80 km) trip could be done in less than a day. The time and the cost for transit dropped as regular paddle wheel steamships and sailing ships went from ports on the east coast and New Orleans, Louisiana, to Colón, Panama ($80–100), across the Isthmus of Panama by railroad ($25) and by paddle wheel steamships and ...
