Let the speed of the boat in still water be x km/h and the speed of the stream be y km /h .
speed upstream = x-y km/h
speed down stream = x+y km/h
Time taken to cover 15 km upstream = 1 upon x-y hrs
time taken to cover down stream = 22 /x+
total time taken = 8 km /hr
then again u do this method and make a eq. and find x and y .
I hope its help u .
