Answer:
5 mph.
Step-by-step explanation:
Let the runner travel at x miles an hour , then the cyclist travels at 5/ 3 * x
= 5/3 x miles an hour.
So we have the equation
5/3 x - x = 2 ( since the cyclist was travelling at 2 mph faster).,
2/3 x = 2
x = 3/2 * 2 = 3 mph.
So the cyclists speed was 3 * 5/3
= 5 mph.
Perimiter is where you add all the sides and a rectangle has four sides.
28/4=7
But the length is 4m longer then the width so, 7+4=11 but if we do 11+11+7+7= 36. But that is not the perimeter so 7-4=3
And if we do 11+11+3+3=28!
Therefore the length of the rectangle is 11m and the width is 3m
To find the area we just do 11•3=33
The only reason this is long is because i explained and put it into detail but its pretty simple and short once you get the hang of it :)
Slope is (y2-y1)/(x2-x1)
(2-2)/(1-1)
slope is 0 which means it is a horizontal line.
