A wheel 2 feet in diameter turning 10000 revolutions per hour is going, at the rim, 17.45 feet per second, or 25.6 miles per hour.
To figure out how long a revolution is you need to find the circumference of the wheel. If the diameter is 70 centimeters, then to get the circumference you multiply the diameter by pi (3.14). That equals 219.8. centimeters. Then you convert 66 meters into centimeters, and that is 6600. Then you divide 6600 by 219.8 and get 30 revolutions.
0.42 * 13.2=5.544
Diameter = 68 cm => circumference = pi*d = 213.63 cm = 2.1363 m To travel 100 m the wheel makes 100/2.1363 = 46.81 revs.
Diameter = 40 cm implies circumference = 40*pi = 125.7 cm So, in travelling 352 metres = 35200 cm, the wheel will rotate 35200/125.7 = 280.1 times (approx).
The revolutions per minute of a bike wheel depends on the size of the wheel, the speed you are riding, and other factors. It is generally thought it can spin at 2 revolutions per second.

5000 revolutions in 11000m = 1 revolution every 2.2m Circumference is 2.2m Circumference is diameter times pi 2.2m dividied by pi divided by 2 (to go from diameter to radius) = 35.014cm

The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.

If the diameter is 700 mm then the radius is 700/2 = 350mm The circumference of the circle is 2πr = 2π.350 = 2199.115 mm 1 kilometre = 1000 metres = 1000000 mm : 2km = 2000000mm Number of revolutions = distance travelled ÷ circumference of wheel. 2000000 ÷ 2199.115 = 909. 46 revolutions

It will travel: 50*12*pi = 1885 inches rounded to the nearest integer
40 / 5 = 8 8 * 2 = 16 Wheel B turns 16 times.
Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
