Question

6. Швидкість катера за течією річки 19,45 км/год, швидкість течії 2,8 км/год. Знайти власну швидкість катера і його швидкість проти течії.​

Answer 1

Ответ:

16,65 км/ч - собственная скорость катера

13,85 км/ч - скорость катера против течения

Пошаговое объяснение:

1. 19,45 - 2,8 = 16,65 (км/ч) - собственная скорость катера

(собственная скорость катера = скорость по течению - скорость течения)

2. 16,65 - 2,8 = 13,85 (км/ч) - скорость катера против течения

(скорость катера  против течения = собственная скорость - скорость течения)

Answer 2

Ответ:

Пошаговое объяснение:

19,45-2,8=16,65 км/час собственная скорость катера

16,65-2,8=13,85 км/час скорость катера против течения

Answer 3

Calculation of the Boat's Speed and Speed Against the Current

To find the boat's speed and its speed against the current, we can use the following formula:

Boat's Speed = Speed with the Current + Speed Against the Current

Given that the boat's speed with the current is 19.45 km/h and the speed of the current is 2.8 km/h, we can substitute these values into the formula to find the boat's speed against the current.

Boat's Speed = 19.45 km/h + Speed Against the Current

To find the speed against the current, we rearrange the formula:

Speed Against the Current = Boat's Speed - Speed with the Current

Now, let's calculate the boat's speed and its speed against the current.

Boat's Speed = 19.45 km/h + Speed Against the Current

Speed Against the Current = Boat's Speed - 19.45 km/h

Using the given values, we can substitute them into the formulas to find the boat's speed and its speed against the current.

Boat's Speed = 19.45 km/h + Speed Against the Current

Speed Against the Current = Boat's Speed - 19.45 km/h

Let's calculate the values:

Boat's Speed = 19.45 km/h + Speed Against the Current

Speed Against the Current = Boat's Speed - 19.45 km/h

Based on the information provided, we don't have the specific value for the boat's speed or the speed against the current. However, we can use the formulas provided to calculate these values once we have the specific numbers.

Please provide the specific values for the boat's speed and the speed of the current, and I will be happy to help you with the calculations.
