Question

A rhino can run at speeds of about 28 miles per hour. What is that speed in

feet per second, to the nearest whole number? (Remember, there are 5280
feet in a mile, 60 seconds in a minute, and 60 minutes in an hour.)

A. 189 feet per second

B. 41 feet per second

C. 88 feet per second

D. 36 feet per second

Answer 1

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;

`28* 5280=147840`

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;

`Speed=(147840)/(3600)`

`Speed = 41.066667`

Rounding off to the nearest whole number, we get;

`Speed =41`

Therefore, the speed of the rhino is 41 feet per second.

Hence, Option B is the correct answer.
