Answer:
The speed of the current 1 km/hr
Explanation:
It is given that,
A canoe can go 24 KM downstream in three hours. The return trip takes four hours.
Points to remember
Let speed of canoe in still water = x km/hr
Speed of stream or current = y km/hr
Downstream speed with stream speed = x + y
Upstream speed against stream speed = x - y
To find the speed of current
From the given information we can write,
Downstream speed = x + y = 24/3 = 8 km/hr
upstream speed =x - y = 24/4 = 6 km/hr
y = [(x + y) - (x -y)]/2 = (8 - 6)/2 = 1
Therefore the speed of the current = 1 km/hr
