He ran for 12 km in his journey.
<h3>What is an Equation ?</h3>
An equation is formed when two algebraic expressions are equated by an equal sign.
It is given that
Speed of Walking =6km/hr
Speed of Running = 15km/hr
Let he walks and run x hours ( as given)
he covered distance = 21 x km
The total time taken in the journey is 2x
for the same distance
It is also given that
if for the total journey
if he walks walked twice as long on the journey
He walked 6x in the journey so new distance that he walked is 12x , then the total journey time = 6 minutes longer
Converting speed from km / hr to km/ min
1 km / hr = 60 km/ min
and forming an equation with the given data
12x * 60 /6 + 9x *60/15 = 2x * 60 + 6
120x + 36x = 120x +6
150x = 120
x = 120/150
x = 0.8 hours.
Therefore he spent 0.8 hours walking and 0.8 hours running and He ran 15 * 0.8 = 12 km

Hey there! I'm happy to help!
The median is the line cutting the triangle in this graph. In general, a median connects any of the triangle points to halfway across the side opposite to that point. This median connects R to halfway across the side across from R.
We want to find the equation of this median. We see that T is at (-2,3) and R is (3,-3). The first thing to do when looking for the equation of the line is to find the slope, or incline. Since we have two points, we can do this very easily. You simply divide the difference in the y-values by the difference in the x-values.
DIFFERENCE IN Y-VALUES
3-(-3)
3+3
6
DIFFERENCE IN X-VALUES
-2-3
-5
Now, we divide the two answers, giving us -6/5.
So, we have our slope, which gives us the equation so far y=-6/5x+b. We just need to find the b, which is our y-intercept. Well, to do this, we plug in one of our points and we can solve for b. We will use (3,-3)!
-3=-6/5(3)+b
-3=-3 3/5+b
We add 3 3/5 to both sides to isolate the b.
b=3/5
This means that this median should hit the y-axis at (0,3/5), and it looks like it does. Therefore, the equation of this median is y=-6/5x+3/5.
Now you can find the slope of a median! Have a wonderful day! :D

Step-by-step explanation:
it's what I got mate
Put x over 1 and start @ -1 on the graph
Then put 2 over 1 and start @ -2 on the graph
Do the same thing with the other graph
