WORLD HISTORY

Detailed explanation-1: -On Oct. 28, 1942, a “Patriotic Speed Limit” of 35 mph was announced in an attempt to conserve gasoline and save on tires during World War II, according to the official history of the Utah Highway Patrol.

Detailed explanation-2: -In 1974, the federal government passed the National Maximum Speed Law, which restricted the maximum permissible vehicle speed limit to 55 miles per hour (mph) on all interstate roads in the United States. The law was a response to the 1973 oil embargo, and its intent was to reduce fuel consumption.

Detailed explanation-3: -What is the speed limit in the USA? The maximum speed limit on rural interstate highways is 70mph, with a 45mph minimum. On four-lane divided highways, the limit is 65mph, and on all other highways it’s 55mph. If you are driving through a designated school zone, you must drop to 15mph.

Detailed explanation-4: -First instituted in 1901, speed limits are assigned to increase road safety and reduce the risk of traffic collisions. For a long period, individual states were responsible for determining their own speed limit laws. After oil shortages in the 1970s, Congress established a national maximum speed limit of 55 mph.

Detailed explanation-5: -Statutory speed limits are established by State legislatures for specific types of roads (e.g., Interstates, rural highways, urban streets) and can vary from State to State. They are enforceable by law and are applicable even if the speed limit sign is not posted.

Detailed explanation-6: -You were expected to amble up to 50 mph and stay right there. Secondly, there were fewer cars on the road. In 1960 the USA had 61.6 million registered automobiles.

Detailed explanation-7: -The inequality representing speeds less than 55 mph is x < 55. To graph this on the number line, we draw an. However, Timmy could also drive at exactly 55 mph, which is the posted speed. The inequality representing speeds 55mph and under is: x is less than or equal to 55mph.
