Question

What is the velocity of the boat from point x to point y

Answer 1

The distance between the points X and Y is,

`\begin{gathered} d=9\text{ km} \\ =9000\text{ m} \end{gathered}`

The time taken to move the distance is,

`\begin{gathered} t=12\text{ min} \\ =12*60\text{ s} \end{gathered}`

The velocity is given by,

`\begin{gathered} v=(d)/(t) \\ =\frac{9000\text{ m}}{12*60\text{ s}} \\ =12.5\text{ m/s} \end{gathered}`

Hence the velocity is 12.5 m/s.
