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

Answer:

89.5 feet per second

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:

$\begin{gathered} \frac{61miles}{\text{hour}}=\frac{61\times5280feet}{3600\text{ seconds}} \\ =89\frac{7}{15}\text{ feet per second} \\ \approx89\text{ feet per second} \end{gathered}$
