4.At point P,the car must be?

a.travelling at constant velocity

b.climbing a hill

c.accelerating

d.decelerating

5.At point Q,the car must be?

a.travelling downhill

b.stationary

c.reducing speed

d.travelling in the revers direction

[Explanation]

4. Based on the line graph the car P must be accelerating, because based on the line the car's speed is so high that's why my answer is c.accelerating, because if you answer b.climbing a hill it is impossible that car can climb! if the answer is the car is travelling a hill i might doubt that its an answer too.

5. Based on the line graph the car Q is must be c.reducing speed because the car is speed is so high that the might crash that's why my answer is c. reducing speed.
