Answer:

100 km/hr and 80 km/hr

Step-by-step explanation:

1st case :

             distance travelled by train = 300km

                       and by taxi = 200km

   

         Let speed of train be x km/hr     and     that of taxi be y km/hr.

                  

     so, time taken by train = d/s                        time taken by taxi = d/s

                                      = 300/x                                                = 200/y

  

               total time taken = 5hrs 30 mins = 5 1/2 hrs

                                 

          so, 300/x +200/y = 5 1/2 by solving we get : 600y + 400x = 11xy..........1

2nd case :

          

           distance travelled by train = 260 km          and by taxi = 240 km

          

    here also speed of train be x km/hr and of taxi be y km/hr

 

 Then time = d/s

         train time= 260/x hr                            of taxi = 240/y hr

       combiningly,total  time =

 

                            260/x + 240/y = 5hrs 36 mins

                      =>  or 260/x + 240/y = 5 3/5   on solving we get,

  

                     1300y + 1200x = 28xy...............2

eq 1 × 3 = 1800y + 1200x = 33xy
