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.

Answer:
Domain: {9, 8, 7, -5} Range: {1, -3, 5, 3}
Step-by-step explanation:
The domain is the list of first numbers in the ordered pairs. If any of those are repeated, the relation is not a function.
The range is the list of second numbers in the ordered pairs.
The domain and range of C are shown above.
Answer:
Do you mean solve for t?
If you do, the answer is 9.
Step-by-step explanation:
If we expand the equation out, we get:
-t = 9t - 90
If we move the -90 over to the left side and the -t to the right side, we get:
90 = 10t
Dividing both sides by 9, we get:
t = 9
