HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A position-time graph is shown.

Graph of position versus time with time on the x axis in seconds and position on the y axis in meters. The graph starts at 0, 0 and then curves through 1, 4 and then 2, 5.5 and then 3, 6.5 and then 4, 6.7.

Calculate the slope of the line segment from t = 1 s to t = 2 s. (4 points)

A.0.75 m/s

B.1.5 m/s

C.2.8 m/s

D.5.5 m/s

please give fast will give brainlest !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

B) 1.5 m/s

Step-by-step explanation:

We have to find the slope of the line segment that starts at (1,4) and ends at (2, 5.5).

We can find the slope using the formula,

    [tex]\boxed{\bf Slope = \dfrac{y_2-y_1}{x_2-x_1}}[/tex]

                [tex]\sf =\dfrac{5.5-4}{2-1}\\\\\\=\dfrac{1.5}{1}\\\\\\= 1.5 \ m/s[/tex]
