The speed of the ship against the stream of the river is 24.8 km / s, and the speed of the current is 2.6 km / h. Find the speed of the boat along the river.
1. If a motor ship is sailing along a river, then the speed of its movement is equal to the sum of its own speed and the speed of the current. And if the ship is sailing against the current, then the speed of movement is equal to the difference between its own speed and the speed of the river.
2. Let us determine the own speed of the motor ship, as if it were moving in standing water. Its own speed is equal to: 24.8 km / h + 2.6 km / h = 27.4 km / h.
3. Let’s determine the speed of the motor ship if it moves along the river:
27.4 km / h + 2.6 km / h = 30 km / h.
Answer: the speed of the motor ship when moving along the river is 30 km / h.
