The rate that train 1 is going plus the distance:

35x+52.5

The rate that train 2 is going plus the distance:

56x+0

X=number of hours

Solve for X to find where the 2 trains have gone the same distance:

35x+52.5=56x
52.5=21x
2.5=x

The express train will overtake the local train 2 and a half hours after it leaves

Answer: A.(3x,3y)

Step-by-step explanation:

In the given graph,

Triangle A'B'C' is an image of Triangle ABC after dilation.

Algebraic rule for dilation (with center =origin)

$(x,y)\to (kx,ky)$ , where k= scale factor.

Coordiantes of A = (1,1) Coordinates of A' = (3,3)

Scale factor = $\dfrac{\text{x-coordinate in image}}{\text{ x-coordinate in pre-image}}$

$=\dfrac31=3$

Hence, the required algebraic rule : (3x,3y)

The correct option is A.
