Just one. Hope this helps!
<span>You are given a car moved at a constant velocity during the first hour. It stopped for 2 hours at a mall and then moved ahead again at a constant velocity for the next 3 hours. Then you are given the car that has finally returned to its starting point with a constant velocity in the next 2.5 hours. The graph that best represents the car's motion is First straight line joins ordered pairs 0, 0 and 1, 60, second straight line joins 1, 60 and 3, 60, third straight line joins 3, 60 and 6, 100 and fourth straight line joins 6, 100 and 8.5, 0.</span>
Answer:
y = - 24
Step-by-step explanation:
Descent time: 4.25 min
hover time: 12.75 min
19.125 - 4.25-12.75 = 2.125 min
So, the ascent rate was (-28.9 - (-79.9))ft/2.125min = 24.0 ft/min
The answer would be A because 3.90 x 3.5 is equal to 13.65
