Answer:

25 rotations

Step-by-step explanation:

To find the number of degrees it rotates in an hour, multiply 107 by 60 (since there are 60 hours in a minute). This gets us 6420. As we know, 360 degrees makes a full rotation, so we need to divide 6420 by 60. This gets us 24.6923076923. We need to round this to the nearest whole number. Since the first decimal number is a 6, we round up to 25. That means it makes about 25 rotations in an hour.

Answer:

18 rotations.

Step-by-step explanation:

As there are 360 degrees in a circle, by proportion, the time for 1 rotation

= (360/107) * 1

= 3.364 minutes.

So the number of rotations in 1 hour (60 minutes)

=  60 / 3.364

= 17.83
