A bicycle should not make any rotations! The number of rotations made by the wheels of a bicycle will depend on the wheel size.
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
13.369 rotations, and 12.368 cycles of phases.

During each complete revolution around the sun, the earth makes 365.24 rotations on its axis.
it takes 365 rotations to make a year
it is not measured by the rotations you make but how long you keep it up.
It depends on the wind and the rating for the windmill
Not counting rotations, there are 4.
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.
Roughly 1/24th or 0.04167 of one revolution.

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)
