If two object experiences the same displacement at the same time, the two objects must have the same average velocity.
The average velocity of an object is defined as the change in displacement per change in time of motion. This can be written as follows;
If two object experiences the same displacement at the same time, it means that the change in displacement with time is constant.
Thus, we can conclude that if two object experiences the same displacement at the same time, the two objects must have the same average velocity.

Answer:
The normal force experienced by the car is approximately 8223.2 N
Explanation:
The question relates to banking of road where the centripetal force for the circular motion of the vehicle is provided by the horizontal component of the normal reaction
The mass of the vehicle that moves around the curve, m = 900 kg
The incline of the curve, θ = 20°
The speed with which the vehicle moves around the curve, v = 12.5 m/s
The radius of the curve, R = 50 meters
We have;
Where;
θ = The angle of inclination of the road = 20°
N = The normal force experienced by the car
m = The mass of the car = 900 kg
v = The velocity with which the car is moving = 12.5 m/s
R = The radius of the curve around which the vehicle moves = 50 m
The normal force experienced by the car = N ≈ 8223.2 N.
