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:

Question 7

Step1: Recall velocity formula

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

Step2: Identify values and substitute

Given $d = 10$ km (west - direction matters for velocity) and $t=3$ hours. Substitute into the formula: $v=\frac{10}{3}$ km/h west.

Step1: Recall time - velocity - distance formula

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

Step2: Identify values and substitute

Given $d = 12$ km (north - direction for displacement) and $v = 6.5$ km/h. Substitute into the formula: $t=\frac{12}{6.5}=\frac{120}{65}=\frac{24}{13}\approx1.85$ hours.

Answer:

$\frac{10}{3}$ km/h west
