Question

1. what is the velocity of a motorcycle traveling 10 km west in 3 hours? equation: plug numbers into the equation final answer w/ units 8. how much time does it take a person to walk 12 km north at a velocity of 6.5 km/h? equation: plug numbers into the equation final answer w/ units

Explanation:

Step1: Recall velocity formula

The formula for velocity is $v=\frac{d}{t}$, where $v$ is velocity, $d$ is displacement, and $t$ is time.

Step2: Plug in values for motorcycle problem

Given $d = 10$ km and $t=3$ hours. So $v=\frac{10}{3}\approx3.33$ km/h west.

Step3: Recall time - displacement - velocity relation for second problem

The formula for time is $t = \frac{d}{v}$, where $d$ is displacement and $v$ is velocity.

Step4: Plug in values for walking problem

Given $d = 12$ km and $v = 6.5$ km/h. So $t=\frac{12}{6.5}\approx1.85$ hours.

Answer:

1. Equation: $v=\frac{d}{t}$

Plug numbers into the equation: $v=\frac{10}{3}$
Final Answer w/ units: $3.33$ km/h west

1. Equation: $t=\frac{d}{v}$

Plug numbers into the equation: $t=\frac{12}{6.5}$
Final Answer w/ units: $1.85$ hours
