Is 20 mph Fast For a Human? Yes, If you run the entire hundred metres in 20mph, you will get a time of 11.1 seconds.
So far, the fastest anyone has run is about 27½ miles per hour, a speed reached (briefly) by sprinter Usain Bolt just after the midpoint of his world-record 100-meter dash in 2009. This speed limit probably is not imposed by the strength of our bones and tendons.
Humans could perhaps run as fast 40 mph, a new study suggests. Such a feat would leave in the dust the world's fastest runner, Usain Bolt, who has clocked nearly 28 mph in the 100-meter sprint. The new findings come after researchers took a new look at the factors that limit human speed.
Yes, 15mph is very fast for a runner as it equates to a 4-minute mile. 15mph represents the fastest a human can run, with extensive training, for a distance of 1 mile to 2 miles. Sprinters can run faster, but obviously for a much shorter duration. Usain Bolt has hit 28mph in the 100m sprint.
Yes, 20.5 miles per hour is fast for humans in general.

The questions remain: how fast and how much faster can he go? According to Fox News, humans—who top out at roughly 23 mph—may one day be able to reach phenomenal speeds of up to 40 miles per hour. If the muscle fibers that get feet off the ground are maximized, top speeds of 40 miles per hour could be reached.
People running for their lives, not for recreational purposes, can run at an average speed of 12 mph. Athletes and gym enthusiasts tend to be faster than the average person and may run at a speed as high as 14 to 17 mph. The numbers change when referring to endurance and long-distance trails.

48 km/hMaximumCat/SpeedBolt's record-setting runs probably place him around 30th on the list of the fastest, behind the white tail deer, warthog, grizzly bear, and house cat (which can hit speeds of about 30 mph). And yet there are very few animals that could beat a man in a marathon or longer distance race.
27.33 miles per hourIn 2011 Belgian scientists used lasers to measure Bolt's performance in the different stages of a 100-meter race held in September that year. They found that, 67.13 meters into the race, Bolt reached a top speed of 43.99 kilometers per hour (27.33 miles per hour).
Pontoon boat speeds can surpass 30 MPH under the right conditions, with a few pontoon boats even reaching the 35 MPH mark thanks to larger engines and great conditions. This boat's combination of speed and strength gives it a top boat speed of around 25 MPH, even when you have a few friends aboard weighing it down.
Knots, on the other hand, are used to measure speed. One knot equals one nautical mile per hour, or roughly 1.15 statute mph.
30 miles per hourBobcats are excellent climbers and can run up to 30 miles per hour (48 kilometers per hour). They stalk their prey with unparalleled patience, and often travel 2 to 7 miles (3 to 11 kilometers) in an evening while hunting and patrolling their territory.

One knot equals one nautical mile per hour, or roughly 1.15 statute mph. The term knot dates from the 17th century, when sailors measured the speed of their ship using a device called a “common log.” The common log was a rope with knots at regular intervals, attached to a piece of wood shaped like a slice of pie.

50 mph on the water in a boat up to about forty feet will feel fast, however on a high speed surface craft like a passenger hydrofoil like the Rodriguez 140, 160, 200 etc. it will feel quite slow. Racing boats run from around forty for small junior classes to in excess of 220 mph in class one offshore racing.

1 Barry Allen (Earth-Prime) Barry Allen is known as the Fastest Man Alive, and that isn't just a cute nickname. Eobard Thawne said that the speed of Barry is potentially unlimited. He reached Mach 13.2 from tachyons and continued to increase his speed to even faster levels since that time.
Superhuman Speed: Wally is capable of moving at incredible superhuman speeds. He was able to cover 7,000 miles in 6.25 seconds, and even accelerate far beyond light-speed to the point of entering the Speed Force dimension. He is faster than both Superman and Barry Allen, having beaten both in separate races.
After your glucose and glycogen are depleted, your body will begin to use amino acids to provide energy. This process will affect your muscles and can carry your body along for about three days of starvation before metabolism makes a major shift to preserve lean body tissue.
