Question

an antelope can run at a speed of 61 miles per hour what is this speed in feet per second remember one mile equals 5280 feet

Answer 1

89.5 feet per second

Step-by-step explanation:

The speed of the antelope in miles per hour = 61 miles per hour

Now, we have the standard unit of conversion:

`\begin{gathered} 1\text{ mile=5280 feet} \\ 1\text{ hour =3600 seconds} \end{gathered}`

Therefore:

`\begin{gathered} \frac{61miles}{\text{hour}}=\frac{61*5280feet}{3600\text{ seconds}} \\ =89(7)/(15)\text{ feet per second} \\ \approx89\text{ feet per second} \end{gathered}`
