Answer:
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
