Using the relation between velocity, distance and time, it is found that her average speed for the final 30 miles is of 55.56 mph.
<h3>What is the relation between velocity, distance and time?</h3>
Velocity is distance divided by time, that is:

Simone travels 90 miles at an average speed of 40 mph, hence the time is given by:

She then travels a further 30 miles, with an average speed for the journey of 43 mph. Hence, she traveled 90 + 30 = 120 miles, and the total time is given by:

Hence, in the second part, she traveled 30 miles in 2.79 - 2.25 = 0.54 hours, so the velocity is given by:

Her average speed for the final 30 miles is of 55.56 mph.

Point A is an outlier because if we were to put the best fit line along with the points according to the most amount of points, point A is the farthest away from the line and thus is the outlier.
