Question

сколько километров пройдёт моторная лодка за 4 часа двигаясь против течения реки, если её собственная скорость 22 км/ч, а скорость течения составляет 1 дроб 11 собственной скорости лодки.​

Answer 1

Ответ:

Пошаговое объяснение:

1)2/11*22=4 (км/ч) -скорость течения 2)22-4=18 (км/ч)- скорость против течения 3)4*18=72 (км) - пройдёт моторная лодка за 4 часа Ответ:72 км. Удачи!

Answer 2

Ответ: 80 км

Пошаговое объяснение:

1) 22 * 1/11 = 2 км/ч - скорость течения

2) 22 - 2 = 20 км/ч - скорость против течения

3) 20 * 4 = 80 км - расстояние

Answer 3

Calculation of Distance Traveled by the Motorboat

To calculate the distance traveled by the motorboat in 4 hours while moving against the current of the river, we need to consider the boat's own speed and the speed of the current.

Given: - Boat's own speed: 22 km/h - Speed of the current: 1/11 (1 divided by 11) of the boat's own speed

To find the effective speed of the boat against the current, we subtract the speed of the current from the boat's own speed:

Effective speed of the boat against the current = Boat's own speed - Speed of the current

Let's calculate the effective speed:

Effective speed = 22 km/h - (1/11) * 22 km/h

Simplifying the equation:

Effective speed = 22 km/h - 2 km/h

Effective speed = 20 km/h

Now, we can calculate the distance traveled by the motorboat using the formula:

Distance = Speed * Time

Distance = 20 km/h * 4 hours

Distance = 80 kilometers

Therefore, the motorboat will travel 80 kilometers in 4 hours while moving against the current of the river.

Please note that the calculations are based on the information provided and may not account for other factors such as changes in the current or variations in the boat's speed.
