Given:
A rhino runs at a speed of about 28 miles per hour.
We need to determine the speed in feet per second.
Converting miles to feet:
The miles can be converted to feet by multiplying 5280 with 28 miles per hour.
Thus, we have;
[tex]28\times 5280=147840[/tex]
Thus, the speed of the rhino in feet per hour is 147840
Converting hours to seconds:
The hours can be converted into seconds by dividing 147840 by 3600 (Because an hour has 60 seconds in a minute and 60 minutes in an hour)
Thus, we get;
[tex]Speed=\frac{147840}{3600}[/tex]
[tex]Speed = 41.066667[/tex]
Rounding off to the nearest whole number, we get;
[tex]Speed =41[/tex]
Therefore, the speed of the rhino is 41 feet per second.
Hence, Option B is the correct answer.
