Question

The speed of sound is about 4051180.32 feet per hour. Find the speed of sound in feet per second.

Answer 1

The speed of sound is:

4051180.32 feet /hour

We know that.

`\begin{gathered} 1hour=60min \\ 1min=60sec \end{gathered}`

Therefore:

`\begin{gathered} 4051180.32*(feet)/(hour)*(1hour)/(60min)*(1min)/(60sec) \\ \\ 4051180.32*(feet)/(sec)*(1)/(60*60)=1125.33(feet)/(second) \\ \end{gathered}`

The asnwer is: 1125.33 feet/sec.
