• Let length of track be X.
  When A travels X, in the same time B travels X-15.
  When A travels X, in the same time C travels X-25.
  Thus, We can say ratio of speeds of B:C is (X-15)/(X-25)....(Time is same or constant)
  When B travels X, in the same time C travels X-15.
  Thus, ratio of speeds of B:C is also given by (X)/(X-15)...
  (X-15)/(X-25) = (X)/(X-15)...solving this, we get 45...
