Question

1. if the velocity of a car is 45 km/h west, how far can it travel in 0.5 hours? equation: plug numbers into the equation final answer w/ units 10. what is the velocity of a rocket that goes 700 km north in 25 seconds? equation: plug numbers into the equation final answer w/ units

Explanation:

Step1: Identify the formula

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

Step2: Plug in the values for the car problem

Given $v = 45$ km/h and $t=0.5$ h. So $d=45\times0.5$.

Step3: Calculate the distance for the car

$d = 22.5$ km.

Step4: Identify the formula for the rocket problem

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

Step5: Plug in the values for the rocket problem

Given $d = 700$ km and $t = 25$ s. So $v=\frac{700}{25}$.

Step6: Calculate the velocity for the rocket

$v = 28$ km/s.

Answer:

1. Equation: $d = v\times t$

Plug numbers into the equation: $d=45\times0.5$
Final Answer w/ units: 22.5 km

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

Plug numbers into the equation: $v=\frac{700}{25}$
Final Answer w/ units: 28 km/s
