(x+4)\[\frac{ 120 }{ x+4 }=\frac{ 120 }{ x }+1\] x is the rate at which B is travelling (ie. xkm/h)

There SOLVE FOR x

Wait it's incorrect for some reason. I made a mistake.

120/(x+4) =120/x +1 120/(x+4) =(120+x)/x 120x =(120+x)(x+4) 120x =120x +480 +x^2 +4x x^2 +4x +480 =0

That's the problem.

which has NO real SOLUTION

It is should be 120/(x+4) =120/x -1
anonymous

Beacuse A takes 1 hour less than B

it's not +1 it's -1

-2 + 21.82i or -2-21.82i

\[\frac{ 120 }{ x+4 }=\frac{ 120 }{ x }-1\]

I previously wrote +1
anonymous
  • anonymous
instead of -1
anonymous
  • anonymous
oh really sorry, I have a mistake. x=24.
anonymous
  • anonymous
That's incorrect still. Try again.

  • anonymous
really?? . so, x=20, right??? Don't tell me it's still incorect ..:(
