Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:

Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":

Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:

Answer:
A
Step-by-step explanation:
A. because the first point shows her acceleration and you can see her speed increasing when she hits the second point, so we can say that see accelerated up the ramp and after it hits the third point her speed becomes constant all the way when she reached the highway
1) + $12, since it is a profit
2) -1440 ft, since it is below the sea level
3) - 22°F, since it is below
4) + 31 yards, since it is a gain.
