Answer:
Speed of Chris Huber = 30.726 m/s
Time taken by Sam = 5.55 s
Step-by-step explanation:
Given:
Distance = 200 m
Time taken by Chris Huber = 6.509 s
Now,
Speed of Chris Huber = 
or
Speed of Chris Huber = 
or
Speed of Chris Huber = 30.726 m/s
Speed of Sam = Speed of Chris Huber + 19.0 km/h
Now,
1 km/hr = 0.277778 m/s
thus,
19.0 km/h = 19.0 × 0.27 = 5.278 m/s
thus,
Speed of Sam = 30.726 + 5.278 = 36.004 m/s
therefore,
Time taken by Sam = 
or
Time taken by Sam = 
= 5.55 s
The equation of the graph, in slope-intercept form, is: C. y = 2/3x + 6.
<h3>How to Write a Linear Equation in Slope-Intercept Form?</h3>
The linear equation of a graph in slope-intercept form is expressed as y = mx + b. Where the variable in the equation are as follows:
- b = y-intercept (this is the point on the y-axis where the line intercepts).
- m = slope (this is the rise/run along the line = change in y / change in x).
Considering the graph given, to write the linear equation it represents, find the slope (m) and the y-intercept (b) of the line.
Slope (m) = rise/run = 2 units/3 units
Slope (m) = 2/3.
The line intercepts the y-axis at y = 6, thus, the y-intercept (b) would be 6. b = 6.
Substitute m = 2/3 and b = 6 into the slope-intercept form equation, y = mx + b:
y = 2/3x + 6
Thus, the equation, in slope-intercept form, that represents the linear graph as shown in the image given is: C. y = 2/3x + 6.
