Question 761073
150/(x - 2) - 125/x = 25
Denominator= x(x - 2)
150x - 125(x-2) = 25(x(x-2))
150x - 125x + 250 = 25x^2 - 50x
Rearrange
25x^2 - 50x - 150x + 125x + 250 = 0
25x^2 - 75x + 250 = 0
Divide by 25
  x^2 - 3x + 10 = 0
 (x - 5)(x + 2) = 0
So x = -2 (no answer)
x = 5
Proof
150/(5 - 2) - 125/5  = 25
150/3 - 125/5 = 25
  50  -  25  = 25
50km/hr and 25 km/hr
Hope this helps.
