Yes.
Let speed of stream = y kmph & speed of boat = x kmphspeed downstram((x + y)kmph) = 8 * 60 / 40 kmph= 12 kmphspeed upstream((x - y) kmph) = 8/1 kmph= 8 kmphx + y = 12x - y = 8--------------2x = 20,2y = 4x = 10,y = 2=>Speed of stream = 2 kmph, Speed of boat = 10 kmp
it depends on the speed of the vehicle I.E if its speed it 600 kmph then it will take 1 hour , It it is 300 kmph then 2 hour if u tell the exact speed the answer would be more accurate.... GOOD LUCK!
