Answer:
8 weeks
Step-by-step explanation:
Let x represent how many weeks they will be in France.
The tour in Britain can be represented by 2x, since it is twice as long as the one in France.
The tour in Germany can be represented by x - 2, since it is 2 weeks shorter.
Create an equation and solve for x:
(x) + (2x) + (x - 2) = 30
4x - 2 = 30
4x = 32
x = 8
So, they will be in France for 8 weeks

Step-by-step explanation:
Coordinates of A≡(−1,3)
Coordinates of B≡(7,9)
Coordinates of C≡(15,-3)
The median through the vertex C will meet at the mid point of AB.
Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)
Now,
Length of median through vertex C= Distance between (15,-3) and (3,6)
Therefore,
Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit
Hence the length of median through the vertx C is 15 units.
