Question

An object is moving at a speed of 6 feet per year. Express this speed in miles per year. Round your answer To the nearest thousandth

Answer 1

We know that 1 mile is equivalent to 5280 feet. So we have that

`6(ft)/(year)=6(ft)/(year)*((1mile)/(5280ft))`

which gives

`\begin{gathered} 6(ft)/(year)=6(ft*1mile)/(year*5280ft) \\ 6(ft)/(year)=(6)/(5280)(mile)/(year) \end{gathered}`

Therefore, we get

`6(ft)/(year)=0.0011363(mile)/(year)`

By rounding to the nearest thousandth, the answer is:

`0.001(mile)/(year)`
