Question

Jodie bicycles 8 km/c faster than Javier.  In the same time it takes Javier to bicycle 57 km, Jodie can bicycle 81 cm.  How fast does each bicylist travel?

anonymous · Answer

suppose the speed of jevier's cycle is x.
         hence speed of jodie's cycle = x+8.

  =>   57/x=81/(x+8)     
  =>    81x=57x + 8*57
  =>    81x-57x=8*57
  =>    24x=8*57
  =>        x=19 
               x+8= 19+8=27.
