Answer:
E to F
Explanation:
We know that v = dx/dt
and a = d²x/dt²
Decreasing velocity means deceleration or negative acceleration,
therefore d²x/dt²<0
i.e the portion where the graph is having its curvature downwards like an inverted u, from graph E to F portion looks like that.
Therefore in the portion E to F velocity decreases.
The speed limit would be 70.2 mi/h
