A person meets the criteria for permanent blindness under section 95 of the Social Security Act if the corrected visual acuity is less than 6/60 on the Snellen Scale in both eyes or there is a combination of visual defects resulting in the same degree of permanent visual loss. [34]
The running speed of 71 mph (114 km/h) of the cheetah was obtained as an result of a single run of one individual by dividing the distance traveled for time spent. The run lasted 2.25 seconds and was supposed to have been 73 m (240 ft) long, but was later found to have been 59 m (194 ft) long.
Limitations of animal running speed provides an overview of how various factors determine the maximum running speed. Some terrestrial animals are built for achieving extremely high speeds, such as the cheetah , pronghorn , race horse and greyhound , while humans can train to achieve high sprint speeds.

How the cheetah became the company's symbol. Brown & Brown Chairman J. Hyatt Brown credits Linda Downs, the company's then-executive vice president, for coming up with the idea in either 1986 or 1987.
The highest speed reliably and rigorously measured in cheetahs in a straight line is 29 m/s (104 km/h), as an average of 3 runs over a 201.2-meter (220 yards) course (starting from start line already running). [61] [62] Top speed data is result of dividing distance by time spent. Pronghorn: 80–96 km/h (50–60 mph) [19] [27] [22]

A person taking the test covers one eye from 6 metres or 20 feet away, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that specific eye. The symbols on an acuity chart are formally known as "optotypes". Variation of Snellen chart with another letter ...
