C. It is a basic parabola
There is a line and a parabola in the graph.
So, we will get the solution set from the point of intersection of both line and parabola.
Notice that the parabola and the line intersecting at two points E(1, 5) and C(-0.5,2).
So, the solution set is E(1, 5) and C(-0.5,2).
Distance = rate*time
time = distance/rate
2.5 hours or 150 minutes
V(s) = s^3 should be the correct answer. Hope this Helps!
