Question

It takes a person 42 seconds to swim in a straight line from the west end of apool to the east end of the pool, a distance of 45 meters. What is theswimmer's velocity?OA. 1.1 m/s westOB. 0.9 m/s eastOC. 1.1 m/s eastD. 0.9 m/s west

Answer 1

Given

Time taken, t=42 sec

The distance travelled is d=45 m

To find

The swimmer's velocity

Step-by-step explanation

The velocity is the ratio of the distance to time

Thus,

`\begin{gathered} v=(d)/(t) \\ \Rightarrow v=(45)/(42)=1.1\text{ m/s} \end{gathered}`

The velocity is directed from west to east.

Conclusion

The swimmer's velocity is

C. 1.1 m/s east
