The Wolf Spider didnât get its name because it howls at the moon, disguises as your Grandma, or blows down pig dwellings. Rather, the nocturnal Wolf Spider is an agile hunter, searching out and consuming its prey at night instead of luring it into a web, like other spiders (and yes, like a wolf).
Canadian speed limits have been posted in kilometres per hour (km/h) since 1977.Before then, when Canada used Imperial units, speed limits were in miles per hour (mph).osted speed limits may differ from the statutory speed limit as indicated by speed limit signs. In most provinces and territories, statutory speed limits are 50 km/h in urban areas, 80 km/h in rural areas.
With the exception of military and scientific usage, the United States does not use the metric system, instead retaining its own customary units. This means that road distances are indicated in miles, and speed limits are indicated in miles per hour (mph). 1 mile is equal to 1.609 km. Canada and Mexico use the metric system; automobile speedometers (but not odometers) normally display both units.
