Some friends went on a trip from A to B via P. Walking from A to P at 6 km/h and the rest of the way at 3 km/h took 1 hour and 40
minutes. If they had walked the first stretch at 3 km/h and the rest of
the way at 2 km/h, it would have taken 3 hours. Find the distance
between A and B.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
