speed = distance/time

distance = 500km

time = 7h

 speed = 500/7 = 71.42957


b]  average distance  = speed*time+speed*time

      case1 = speed = 50 kmph*1  

                     time in hours = 15/60 = 1/4

  case2  speed = 40kmph

               time = 10/60 = 1/6

   average speed= 50*1/4 + 40 *1/6 = 12.5+6.6667    =   19.1667
