Answer:
We know that the sum of the degrees of the vertices of the graph is twice the number of edges of the graph.
Let 
be a graph with vertices 
Then 
where 
is the number of edges of the graph. Since the graph is regular of degree r then all vertices have degree r. Thus,
Answer: 1 mile.
Explanation: 1/2 of an hour is 1 mile because the speed was 2 miles an hour so if you do half of that it is 1 mile.
The answer would be 24.6 cm
