Vehicle movement is given by the equation x = 15t-150. determine the distance

Vehicle movement is given by the equation x = 15t-150. determine the distance of the car from the starting point of movement to the coordinate in which it will be in 15 seconds.

The distance traveled by the car is equal to the difference between the starting and ending points of the car’s location.
x = xk – xn.
The starting point of the vehicle.
Equation of motion: xн = 15t – 150.
Travel time: t = 0.
xо = 15t – 150 = 15 * 0 – 150 = -150.
The end point of the vehicle.
Equation of motion: xk = 15t – 150.
Movement time: t = 15.
xk = 15t – 150 = 15 * 15 – 150 = 75.
Then:
x = xк – xн = 75 – (-150) = 75 + 150 = 225 m.
Answer: The distance traveled by the car is 225 m.
