Given information
Step-by-step explanation
Step 1.
In general, an inflection point is a point where a curve changes its direction of concavity.
The significance of this point is that the rate of change (velocity in our case) has its maximum value there.
The above makes sense because we can see that the slope of the tangent at the inflection point would be the larger then the rest therefore the derivative at that point would be a maximum.
