Depends on the graph.
To determine how many students practiced the piano for more than 3 hours a week, you would need to analyze the data presented in the plot graph. Look for the section of the graph that represents practice times exceeding 3 hours and count the number of students indicated in that range. The total from that segment will give you the answer. If you have the graph, you can visually identify and count those students directly.

The complexity of finding the minimum vertex cover in a graph, also known as the vertex cover problem, is NP-hard.
At walking pace, about 25 hours non-stop.
In graph theory, a vertex cover is a set of vertices that covers all edges in a graph. The concept of a vertex cover is related to the existence of a Hamiltonian cycle in a graph because if a graph has a Hamiltonian cycle, then its vertex cover must include at least two vertices from each edge in the cycle. This is because a Hamiltonian cycle visits each vertex exactly once, so the vertices in the cycle must be covered by the vertex cover. Conversely, if a graph has a vertex cover that includes at least two vertices from each edge, it may indicate the potential existence of a Hamiltonian cycle in the graph.
The vertex cover problem can be reduced to the set cover problem by representing each vertex in the graph as a set of edges incident to that vertex. This transformation allows us to find a minimum set of sets that cover all the edges in the graph, which is equivalent to finding a minimum set of vertices that cover all the edges in the graph.

It will take about 11.5 hours to cover that 720 miles.
It will require about 10 hours of driving time to cover that 627 miles.

A minimum edge cover in graph theory is a set of edges that covers all the vertices in a graph with the fewest number of edges possible. It is significant because it helps identify the smallest number of edges needed to connect all the vertices in a graph. This impacts the overall structure of a graph by showing the essential connections between vertices and highlighting the relationships within the graph.

Distance = rate * time. (55 miles/hour) * (4 hours) = 220 miles
It will take about 15 hours to cover the 1000 or so miles to get to Tucson, Arizona.
