Answer: Third Option

Yes, the person is going 133 miles/hr.

Explanation:

Remember that the average speed can be calculated as

[tex]s = \frac{d}{t}[/tex]

Where s is the speed

d is the distance traveled

t is the time

In this case

[tex]d =4\ miles\\[/tex]

[tex]t=0.03\ hours[/tex]

Therefore

[tex]s = \frac{4}{0.03}[/tex]

[tex]s = 133.33\ miles/hr[/tex]

Remember that the speed limit is 45 miles/hr

So the answer is the third option "Yes, the person is going 133 miles/hr".
