In 30 sec one will have taken 24 steps and the other will have taken 25 steps
and they will be back in step:
Let f1 = 50/min
    f2 = 48/min
    N1 = steps taken by faster stepper (shorter strides)
    N2 = steps taken by longer strider

  N1      = f1 * T(time)
  N1 - 1  = f2 * T     (since N2 takes 1 less step than N1         

   Divide one equation by the other and solve
