Divide P by 4 to move 4 from one side of the equation to the other. s=P/4
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.

Excuse me is that a statement or a question because you do not make it sound like one.
The number equals 33. 1/3 = 11, 2/3 = 22, 3/3 = 33
