Answer 1

Part a)

Car's average speed = Total distance /Total time

$v_{avg}=\frac{d}{\delta t}=\frac{53}{14}=3.8\,m/s$

Part b)

Sign of X-component of car's velocity at any instant is negative (since the car is travelling along negative x-direction)

Part c)

X-component of car's average velocity is $v_{avg,x}=-3.8\,m/s$

Part d)

Yes
