Question

Катер в стоячей воде развивает скорость 24,8 км/ч. Скорость течении реки 1,3 км/ч. Определиье скорость катера: а) по течению реки б) против течения реки

Answer 1

А) Скорость катера по течению реки : 24,8 + 1,3 = 26,1 км/ч
б) скорость катера против течения реки : 24,8 - 1,3 = 23,5 км/ч

Answer 2

По течению 26.1 км\ч
против 23.5 км\ч

Answer 3

Calculation of the Boat's Speed

To determine the speed of the boat in different scenarios, we need to consider the speed of the boat in still water and the speed of the river's current.

Given: - Speed of the boat in still water: 24.8 km/h - Speed of the river's current: 1.3 km/h

We can calculate the boat's speed in different situations as follows:

Speed of the Boat with the Current

When the boat is moving with the current, the speed of the boat will be the sum of its speed in still water and the speed of the current. This can be calculated by adding the two speeds together.

Speed of the boat with the current = Speed of the boat in still water + Speed of the current

Substituting the given values: Speed of the boat with the current = 24.8 km/h + 1.3 km/h = 26.1 km/h.

Therefore, the speed of the boat with the current is 26.1 km/h.

Speed of the Boat against the Current

When the boat is moving against the current, the speed of the boat will be the difference between its speed in still water and the speed of the current. This can be calculated by subtracting the speed of the current from the speed of the boat in still water.

Speed of the boat against the current = Speed of the boat in still water - Speed of the current

Substituting the given values: Speed of the boat against the current = 24.8 km/h - 1.3 km/h = 23.5 km/h.

Therefore, the speed of the boat against the current is 23.5 km/h.

In summary: - The speed of the boat with the current is 26.1 km/h. - The speed of the boat against the current is 23.5 km/h.
