Answer

Explanation:

Step1: Recall velocity formula

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

Step2: Answer first question

Since $v = \frac{d}{t}$, average velocity equals distance travelled divided by time. So the answer to the first question is B.

Step3: Calculate velocity for second case

Given $d = 28$ meters and $t = 4$ seconds. Using $v=\frac{d}{t}$, we have $v=\frac{28}{4}=7$ m/s. So the answer to the second question is A.

Step4: Calculate velocity for third case

Given $d = 60$ meters and $t = 10$ seconds. Using $v=\frac{d}{t}$, we have $v=\frac{60}{10}=6$ m/s. So the answer to the third question is C.

Answer:

First question: B. time Second question: A. 7 Third question: C. 6
