Expert Solution
Step 1
The slope at any point in the position-time graph represents the instantaneous velocity of the object under observation in this situation a car.
also represents the is the angle that the tangent to the curve at that point makes with the x-axis.
Therefore, the more the value, the more will be instantaneous velocity at that point.
