The length of a planet's orbit around a star is approximately 12,450,000 km. It takes the planet about 560 Earth days to complete a full orbit.
What is the planet's average speed in kmh-' to 3sf?

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
