Question

a person drives 512 m toward their home in 25 s. what is the velocity of their car? velocity = ? m/s velocity = \frac{\delta x}{\delta t} round your answer to the nearest tenth.

Explanation:

Step1: Identify the formula

The formula for velocity is $v=\frac{\Delta x}{\Delta t}$, where $\Delta x$ is the displacement and $\Delta t$ is the time - interval.

Step2: Substitute the given values

We are given that $\Delta x = 512$ m and $\Delta t=25$ s. Substituting these values into the formula, we get $v=\frac{512}{25}$ m/s.

Step3: Calculate the result

$v=\frac{512}{25}=20.48$ m/s.

Step4: Round the answer

Rounding 20.48 to the nearest tenth gives $v = 20.5$ m/s.

Answer:

20.5 m/s
