7. what is the velocity of a motorcycle traveling 10 km west in 3 hours? equation: plug numbers into the…

Explanation:

Step1: Recall velocity formula

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

Step2: Identify values for motorcycle problem

For the motorcycle, $d = 10$ km and $t=3$ hours.

Step3: Calculate velocity

$v=\frac{10}{3}\approx3.33$ km/h west.

Step4: Recall time - velocity formula for second problem

$t=\frac{d}{v}$, where $d$ is distance and $v$ is velocity.

Step5: Identify values for walking problem

For the person walking, $d = 12$ km and $v = 6.5$ km/h.

Step6: Calculate time

$t=\frac{12}{6.5}\approx1.85$ h.

Answer:

For the motorcycle: 3.33 km/h west For the person walking: 1.85 h
