Kate takes 30 minutes less time than muthu to travel a distance of 30 kilometers. kate travels 1/3 kilometer per hour faster than muthu . If x is kate 's rate of speed in kilometers per hour, then time taken by kate for the distance is:

• x=30/(T-0.5)
  x-1/3=30/T
  Solving T=6.96 hrs

• time=Distance/Speed
  so
  Muthu's time-kates Time=30 min i.e 1/2 Hours
  30/x -30/1.33x =1/2
  by solving above equation Kate speed=15 km/hr and muthus speed=20 km/hr
