Question

Решите задачу собственная скорость катера равна 21, 6 км ч скорость течения реки 4,7 км ч Найдите скорость катера по течению и против течения

Answer 1

Дано:
 Собственная скорость катера - 21, 6  км/час
 Cкорость течения реки  - 4,7 км/ч 
Для начала найдем скорость против течения, нужно от собственной скорости катера отнять скорость течения:
21,6-4,6=16,9 км/час - против течениям
За течения:
21,6+4,7=26,3 км/час - за течениям

Answer 2

1) 21,6+4,7=26,3км/ч скорость катера по течению

2) 21,6-4,7=16,9км/ч скорость катера против течения реки

Answer 3

Task Solution: Finding Boat Speed with and Against the Current

To find the speed of the boat with and against the current, we can use the following formulas:

1. Speed of the boat with the current (downstream): - Boat speed + Current speed

2. Speed of the boat against the current (upstream): - Boat speed - Current speed

Given: - Boat speed = 21.6 km/h - Current speed = 4.7 km/h

Speed of the Boat with the Current (Downstream):

The speed of the boat with the current is calculated by adding the boat speed and the current speed.

Speed of the boat with the current (downstream) = Boat speed + Current speed Speed of the boat with the current (downstream) = 21.6 km/h + 4.7 km/h Speed of the boat with the current (downstream) = 26.3 km/h.

Speed of the Boat Against the Current (Upstream):

The speed of the boat against the current is calculated by subtracting the current speed from the boat speed.

Speed of the boat against the current (upstream) = Boat speed - Current speed Speed of the boat against the current (upstream) = 21.6 km/h - 4.7 km/h Speed of the boat against the current (upstream) = 16.9 km/h.

Therefore, the speed of the boat with the current (downstream) is 26.3 km/h, and the speed of the boat against the current (upstream) is 16.9 km/h.
