Answer: you will win for any distances greater than 190ft.
To find the rate, you’ll first need to find the slope between two points
Slope formula: m=y^2 - y^1 / x^2 - x^1
Plug the equation in: 76-38/4-2
Substitute. subtract, & divide and you get m=19
Then you have to do slop intercept form:
Formula: y-y1= m(x-x1)
Plug in the equation:
Y-38=19(x-2) substitute
Y-38=19-38 distribute
Y= 19x
Then you graph it (I attached a graph pic)
On the graph there’s two lines that intersect at (10,190). For x less than 10, you will run farther than your friends = you will win.
