Question

A ceiling fan can rotate 150.59 times per minute. The fan rotated a total of 3,764.75 times. Which of the following is true?
A. The fan rotated for 24 minutes
B. The fan rotated for 26 minutes
C. The fan rotated for 25 minutes
D. The fan rotated for 27 minutes

Answer 1

To find out how long the fan rotated in minutes, we can use the formula:

\[
\text{Time (minutes)} = \frac{\text{Total rotations}}{\text{Rotations per minute}}
\]

Given:
- Total rotations = 3,764.75
- Rotations per minute = 150.59

Now, let's calculate the time:

\[
\text{Time (minutes)} = \frac{3,764.75}{150.59}
\]

Calculating that,

\[
\text{Time (minutes)} \approx 24.97
\]

Rounding 24.97 gives us approximately 25 minutes.

So, the correct answer is:

C. The fan rotated for 25 minutes.
