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. 88 feet per second b. 41 feet per second c. 36 feet per second d. 189 feet per second

Explanation:

Step1: Convert miles to feet

To convert 28 miles to feet, we use the conversion factor 5280 feet per mile. So, the number of feet in 28 miles is $28\times5280$ feet.
$28\times5280 = 147840$ feet.

Step2: Convert hours to seconds

There are 60 minutes in an hour and 60 seconds in a minute, so the number of seconds in an hour is $60\times60 = 3600$ seconds.

Step3: Calculate speed in feet per second

Speed is distance divided by time. So, the speed in feet per second is $\frac{147840}{3600}$.
$\frac{147840}{3600} \approx 41$ (rounded to the nearest whole number).

Answer:

B. 41 feet per second
