Let the upstream speed and speed of boat in stillwater be a kilometer per hour and 3a kilometer per hour respectively. Therefore the speed of this stream = 2a Kilometer per hour. And downstream speed of the boat = 2a+3a= 5a Kilometer per hour. According to question, (300/5a) +(20/a) = 10 10a = 80 A=8 Therefore, downstream speed of the boat = 5a=40 a = 8 So X = 40. Time taken by boat To travel to 288 kilometre in Stillwater = 288/24 = 12 hours = ( 0.5*40 – 8 ) = ( 0.5x-8) hrs.
