Upstream components
Distance = 30km
Time = 6hrs
Speed = 30/6 = 5 kmph
Let the speed of the stream be x :
The speed of the boat is x + 5
Downstream. Components
Distance = 30km
Time = 5hr
Speed = 30/5 = 6kmph
Let speed of the stream be x then,
Speed of the boat = 6 - x
Equating the two :
x + 5 = 6 - x
2x = 1
x = 0.5 kmph
Speed. Of the boat = 6 - 0.5 = 5.5kmph
