Answer:
Option A.
Step-by-step explanation:
Consider the below figure attached with this question.
Scenario 1 represented by the graph.
From the graph it is clear that the line passes through the points (1,60) and (2,120).
Slope of the line is
[tex]y=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]y=\dfrac{120-60}{2-1}=60[/tex]
The slope of line is 60. It means the speed is 60 miles per hour.
Scenario 2 defined by the equation,
[tex]y=50x[/tex]
If an equation defined as [tex]y=mx+b[/tex], then m is slope and b is y-intercept.
[tex]m=50[/tex]
The slope of line is 50. It means the speed is 50 miles per hour.
The slope of Scenario 1 is greater than slope of Scenario 2. So, the Scenario 1 shows the greater speed.
Hence, the correct option is A.
