The speed of the river flow is 3.1 km / h, and the speed of the boat against the current is 26.7 km / h. Find the water’s own speed and its speed downstream.
1) Find the boat’s own speed.
To do this, add the speed of the boat against the river flow to the speed of the river.
We get:
3.1 + 26.7 = 29.8 km / h.
2) Find the speed of the boat along the river.
To do this, add the speed of the river to the boat’s own speed.
We get:
29.8 + 3.1 = 32.9 km / h.
Answer:
The boat’s own speed is 29.8 km / h, the speed of the boat along the river is 32.9 km / h.
