The slope of any line on the x-y plane is expressed as the rise divided by the run - the "rise" here is the change in the y coordinate, and the "run" is the change in the x coordinate. Given -4 and 8 as your y coordinates in this problem, and 3 and -1 as your x coordinates, how can you find the change - or difference - in each? Once you have those, you'll just need to put the
V = s/t
now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t
and
340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195
Answer is 195mph
Because it show the relationship between the x and y coordinates
Answer:
That would be 1.5
