The speed of the ship along the river is 52.9 km / h. the speed is 3.2 km / h. find the boat’s own speed and its speed upstream.

To find the speed of the boat, subtract the speed of the current from the speed of the boat downstream:
1) 52.9 – 3.2 = 49.7 (km / h) – speed of the boat.
In order to find the speed of the boat against the current, it is necessary to subtract the speed of the current from the speed of the boat:
2) 49.7 – 3.2 = 46.5 (km / h) – speed of the boat against the current.
Answer: 49.7 km / h is the speed of the boat and 46.5 km / h is the speed of the boat against the current.
