Use D = rt. Distance is 50 miles, rate is 75 miles and time is what we need to find so it is 50 = 75t. Divide both sides by 75. 50/75 = t. 50/75 reduces to 2/3. and 2/3 of 6 minutes is 40 minutes. The answer is 40 minutes to go 50 miles at 75 mph.
Customary units in the United States
United States customary units are a system of measurements commonly used in the United States. The U.S. customary system developed from English units which were in use in the British Empire before American independence. Consequently most U.S. units are virtually identical to the British imperial units. However, the British system was overhauled in 1824, changing the definitions of some units used there, so several differences exist between the two systems.
The majority of U.S. customary units were redefined in terms of the meter and the kilogram with the Mendenhall Order of 1893, and in practice, for many years before. These definitions were refined by the international yard and pound agreement of 1959. The U.S. primarily uses customary units in its commercial activities, while science, medicine, government, and many sectors of industry use metric units. The SI metric system, or International System of Units is preferred for many uses by NIST
The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but some Imperial units are still used in the United Kingdom and Canada.
Miles per hour
Miles Straume is a fictional character played by Ken Leung on the ABC television series Lost. Miles is introduced early in the fourth season as a hotheaded and sarcastic medium as a crew member aboard the freighter called the Kahana that is offshore the island where most of Lost takes place. Miles arrives on the island and is eventually taken captive by John Locke (played by Terry O'Quinn), who suspects that those on the freighter are there to harm his fellow crash survivors of Oceanic Airlines Flight 815 and expose the island to the general public. Miles is on a mission to obtain Ben Linus (Michael Emerson); instead, he tries to cut a deal with Ben to lie to Miles's employer Charles Widmore (Alan Dale) that Ben is dead.
The writers created the role of Miles specifically for Leung after seeing him guest star on The Sopranos. Leung was the only actor to read for the part. They chose his name because it resembles "maelstrom", another word for a powerful whirlpool. Reaction to the character has been positive.
Miles per hour is an imperial unit of speed expressing the number of statute miles covered in one hour. It is currently the standard unit used for speed limits, and to express speeds generally, in many countries throughout the world.
