Answer:
A) 0.4 km/hr
Explanation:
To find the average speed of the car, we have to find the slope of the graph.
We start by locating points. From the graph;
Then we use the relationship:
[tex]m \: = \: \frac{change \: in \: y}{change \: in \: x} [/tex]
Substituting our values;
[tex]m \: = \frac{(4 \: - \: 0) \: km}{(10 \: - \: 0) \: hr } \\ = 0.4 \frac{km}{hr} [/tex]
Therefore, the average speed of the car is 0.4 km/hr. Hence the best choice is (A).
