How fast is 911 kilometers per hour?

It's about 150 times as fast as Michael Phelps
The speed of Michael Phelps is about 6.9930 kilometers per hour.
(at the Beijing Olympics, 2008; 200 m freestyle) (a.k.a. Michael Fred Phelps) (swimmer; 1985-)
Setting a world record, Michael Phelps swam the 200 m freestyle in 1:42.96 for an average speed of 6.993 kph. Phelps would go on to win nine gold medals individually in the 2008 Olympics - more than all but eight of the competing nations.
It's about one-one-hundred-fiftieth as fast as a Meteor
The speed of a Meteor is about 150,000 kilometers per hour.
(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 40,000 kph and 260,000 kph, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 10,000 kph.
It's about 200 times as fast as Walking Pedestrians (in Manhattan)
The speed of Walking Pedestrians (in Manhattan) is about 4.70 kilometers per hour.
(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 4.70 kilometers per hour. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 5.10 kilometers per hour
It's about one-four-hundredth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 350,000 kilometers per hour.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 350,000 kph when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 500 times as fast as an Iceberg
The speed of an Iceberg is about 2 kilometers per hour.
(a.k.a. Berg) (Newfoundland iceberg average)
Moved by ocean currents and wind, icebergs can drift at speeds of about 2 kilometers per hour. The largest iceberg ever recorded was a found near Baffin Island, Nunavut and was estimated to be nine billion metric tons.
It's about 4,000 times as fast as a Sloth
The speed of a Sloth is about 0.240 kilometers per hour.
(for Brown-throated three-toed sloth, Bradypus variegatus)
The three-toed sloth moves along the ground at an average speed of 0.24 kph. Long thought to be lengthy sleepers, a 2008 study concluded that sloths sleep an average of only 9.6 hours per day.
It's about 0.0000009 times as fast as The Speed of Light
The speed of The Speed of Light is about 1,079,252,848.80 kilometers per hour.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 1,079,252,848.80 kilometers per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 719,501,899.2120 kilometers per hour when passing through the glass of a typical window.
It's about 6,500,000,000 times as fast as Grass growing
The speed of Grass growing is about 0.000000140 kilometers per hour.
(for Kentucky Bluegrass, Poa pratensis) (a.k.a. Smooth Meadow grass, a.k.a. Common Meadow grass) (Summer months, ideal growing conditions)
Kentucky Bluegrass, one of the most common grasses in North America, grows about 0.000000150 kilometers per hour in the summer months under ideal conditions. When left un-mowed, Kentucky Bluegrass grows to heights of 60 to 90 cm (2 to 3 ft) and blossoms with a blue flower.
