Ignoring rotations, there are 3 distinct solutions.
IF the fan speed in RPM is given, multiply this figure by 60 to find the number of rotations the fan makes in an hour.
3 miles.
If you mean how many 4 miles make 1 mile then 0.25 If you mean how many 0.4 miles make 1 mile then 2.5
80 miles = 128.75 km

Oil reduces friction between the moving parts of the axles, allowing them to rotate smoothly. This reduces resistance and makes the bicycle easier to pedal. Additionally, oil helps to protect the axles from wear and corrosion, extending their lifespan.
During each complete revolution around the sun, the earth makes 365.24 rotations on its axis.
it takes 365 rotations to make a year
Not counting rotations, there are 4.
it is not measured by the rotations you make but how long you keep it up.
Divide the 62,500 miles/second by the circumference (in miles); that will give you the revolutions per second.Note: If you are given the diameter, you can multiply that by pi to get the circumference; if you are given the radius, multiply that by 2 x pi.
The Earth rotates about 168 times in one week. This is because the Earth completes one full rotation on its axis approximately every 24 hours, resulting in 7 rotations in a week.
Roughly 1/24th or 0.04167 of one revolution.

A typical windmill rotates at around 10 to 25 rotations per minute, although this can vary depending on the design and wind conditions.
365.242, the earth spins for each day, it is not exactly 365.25 days, so we have leap years to make up for it. (oh, by the way, dumb question)
