Answer:
were not moving since there was no change in position
Explanation:
In the given graph, we have the x-axis showing the time they walked and the y-axis showing the distance they moved.
In the interval between 0.75 hours and 1.25 hours, we can note that the distance is remaining constant at 30 km.
This means that during this interval, their distance did not change which implies that they were not walking.
Hope this helps :)

Answer:
a) 2.43 m/s
b) 4.83 m/s
c) 0.023 m/s²
Explanation:
a) Both cars cover a distance of 510 m in 210 s. Since car A has no acceleration
Speed = Distance / Time
Velocity of car A is 2.43 m/s
t = Time taken = 210 seconds
u = Initial velocity
v = Final velocity
s = Displacement = 510 m
a = Acceleration
c)
Acceleration of car B is 0.023 m/s²
b)
Final velocity of car B is 4.83 m/s
