Let the original speed be xkm/h. Therefore 63/x +72/x+6 =3 (solve this equation the value of x will be 42km/h)

As we were asked to find out distance. So distance must be specified with some measurements or units; otherwise it remains absurd. So the word 'units' must be written.

The coordinates of origin is(0,0). The coordinates of the given point is (x,y) . Now, By applying distance formula, we get; Required distance of the given point from origin =√{(x-0)² +(y-0)²} =√(x²+y²) units

Let point be p(x,y) and origin O(0,0). So, distance (PO)=√(0-x)^2+(0-y)^2 PO=√x^2+y^2. And.

The coordinates of origin is (0,0) and the coordinates of given point is (x,y) . So by applying distance formula = root under hole (x-0)square + (y-0) square = root under hole x square + y square

Under root(x-0)2+(y-0)2 = under root X2+y2

The ratio of the area of two similar triangles is equal to the square of there corresponding side (theorm 6.6)therefore the answer is the square of 1/3 which is 1/9
