C: y= 6
Since they are varying inversely, as one gets larger the other gets smaller and vice-versa.
Since when y=3 when x=4.....
When x gets divided by two y would get multiplied by two instead
So y=6 when x=2
here's the image
but i dont know the answer
The formula for the distance between two points is

Note that, if two points have one coordinate in common, this formula simplifies to

(the first if they share the y coordinate, the second if they share the x coordinate).
So, these are the lengths of the sides:

(because they share the y coordinate)

(standard formula)

(because they share the y coordinate)

4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h
