question 7 of 10\nit takes a person 42 seconds to swim in a straight line from the west end of a pool to the east end of the pool, a distance of 45 meters. what is the swimmers velocity?\na. 1.1 m/s east\nb. 0.9 m/s east\nc. 1.1 m/s west\nd. 0.9 m/s west

Answer

Explanation:

Step1: Recall velocity formula

Velocity $v=\frac{d}{t}$, where $d$ is displacement and $t$ is time.

Step2: Identify values

$d = 45$ m (east - direction of motion), $t=42$ s.

Step3: Calculate velocity

$v=\frac{45}{42}\approx1.1$ m/s. The direction is east as the swimmer moves from west - end to east - end.

Answer:

A. 1.1 m/s east
