We know that.
[tex]\begin{gathered} 1hour=60min \\ 1min=60sec \end{gathered}[/tex]
Therefore:
[tex]\begin{gathered} 4051180.32*\frac{feet}{hour}*\frac{1hour}{60min}*\frac{1min}{60sec} \\ \\ 4051180.32*\frac{feet}{sec}*\frac{1}{60*60}=1125.33\frac{feet}{second} \\ \end{gathered}[/tex]
The asnwer is: 1125.33 feet/sec.
