Explanation:

Question 7

Step1: Recall the formula for average velocity

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

Step2: Substitute the given values

Here, \( d = 560\) meters and \( t=54\) seconds. So, \( v=\frac{560}{54}\approx10.37\) m/s.

Step1: Recall the formula for average velocity

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

Step2: Substitute the given values

Here, \( d = 55\) miles and \( t = 1.4\) hours. So, \( v=\frac{55}{1.4}\approx39.29\) mi/hr.

Step1: Recall the formula for time

From the formula \( v=\frac{d}{t} \), we can rearrange it to \( t=\frac{d}{v} \), where \( d \) is distance and \( v \) is velocity.

Step2: Substitute the given values

Here, \( d = 275\) miles and \( v = 65\) miles per hour. So, \( t=\frac{275}{65}\approx4.23\) hours.

Answer:

\( \approx10.37 \)
