Question

1. собтвеная скорость лодки равна 26.4км/ч скорость течения 2.8 км/ч. Найдите скорость лодки потечению и её скорость против течения реки. 2. Скорость катера на подводных крыльях против течения реки равна 58.5км/ч а скорость течения 0.5км/ч Найдите собственую скорость катера и его скорость по течению

Answer 1

Ответ:

Пошаговое объяснение:

26,4+2,8=29,2км/час скорость по течению

26,4-2,8=23,6 км/час скорость против течения

2. 58,5+0,5=59 км/час собств.скорость катера

59+0,5=59,5 км/час скорость по течению

Answer 2

Problem 1: Speed of a Boat in Relation to the Current

To find the speed of the boat relative to the current and its speed against the current, we can use the concept of vector addition.

Given: - Speed of the boat (own speed): 26.4 km/h - Speed of the current: 2.8 km/h

To find the speed of the boat relative to the current, we add the speed of the boat and the speed of the current:

Speed of the boat relative to the current = Speed of the boat + Speed of the current

Substituting the given values:

Speed of the boat relative to the current = 26.4 km/h + 2.8 km/h = 29.2 km/h [[1]].

To find the speed of the boat against the current, we subtract the speed of the current from the speed of the boat:

Speed of the boat against the current = Speed of the boat - Speed of the current

Substituting the given values:

Speed of the boat against the current = 26.4 km/h - 2.8 km/h = 23.6 km/h [[1]].

Therefore, the speed of the boat relative to the current is 29.2 km/h, and the speed of the boat against the current is 23.6 km/h.

Problem 2: Speed of a Catamaran in Relation to the Current

To find the speed of the catamaran relative to the current and its speed against the current, we can use the same concept of vector addition.

Given: - Speed of the catamaran on underwater wings (own speed): 58.5 km/h - Speed of the current: 0.5 km/h

To find the speed of the catamaran relative to the current, we add the speed of the catamaran and the speed of the current:

Speed of the catamaran relative to the current = Speed of the catamaran + Speed of the current

Substituting the given values:

Speed of the catamaran relative to the current = 58.5 km/h + 0.5 km/h = 59 km/h [[2]].

To find the speed of the catamaran against the current, we subtract the speed of the current from the speed of the catamaran:

Speed of the catamaran against the current = Speed of the catamaran - Speed of the current

Substituting the given values:

Speed of the catamaran against the current = 58.5 km/h - 0.5 km/h = 58 km/h [[2]].

Therefore, the speed of the catamaran relative to the current is 59 km/h, and the speed of the catamaran against the current is 58 km/h.

I hope this helps! Let me know if you have any further questions.
