Question

1. Скорость катера x км/ч, скорость реки 2 км/ч. Чему равна скорость катера по течению и против? 2. Скорость катера 20 км/ч, скорость реки x км/ч. Чему равна скорость катера по течению и против?

Answer 1

1)  
х+2 - по течению
х - 2  -против течения

2)
20+х по течению
20 - х  против течения

Answer 2

1. Скорость катера x км/ч, скорость реки 2 км/ч. Чему равна скорость катера по течению и против?

При скорости катера x км/ч и скорости реки 2 км/ч, скорость катера по течению будет равна сумме скорости катера и скорости#### Speed of Boat Relative to River

To calculate the speed of a boat relative to the river, we can use the following formulas:

1. When the speed of the boat is x km/h and the speed of the river is 2 km/h: - The speed of the boat downstream (with the current) is given by the sum of the boat's speed and the river's speed: x + 2 km/h. - The speed of the boat upstream (against the current) is given by the difference between the boat's speed and the river's speed: x - 2 km/h.

2. When the speed of the boat is 20 km/h and the speed of the river is x km/h: - The speed of the boat downstream is given by the sum of the boat's speed and the river's speed: 20 + x km/h. - The speed of the boat upstream is given by the difference between the boat's speed and the river's speed: 20 - x km/h.

These formulas allow us to calculate the speed of the boat relative to the river in both directions.
