Question

5. How many kilometers/hour is a wave traveling if its velocity is 55.523 meters/sec?

Answer 1

first we miltiply by the number of seconds on a hour(3600) to change the unitis to hours

`\begin{gathered} 55.523*3600 \\ =199882.8 \end{gathered}`

so the velocity is 199882.8 meters/hour

now transform the meters on kilometers dividing between 1000

`(199882.8)/(1000)=199.8828`

the new velocity is 199.8828 kilometers/hour
