Answer» onLet’s SAY the distance is x Speed DOWNSTREAM = Speed of Boat + Speed of Stream = 6 kmph + 2 Kmph = 8 kmph Speed Upstream = Speed of Boat - Speed of Stream = 6 kmph - 2 kmph = 4 kmph Time = Distance/Speed Downstream time = x/8 HOURS Upstream time = x/4 hours So for the total journey = x/8 + x/4 = (3/8)x But given total time = 3 hours ==> (3/8) x hours = 3 hours x = 8 km So the distance is 8km and the total distance traveled is 16 km. Good LUCK |
