Question

ПОМОГИТЕ ПОЖАЛУЙСТА!!! Скорость катера против течения 11,3 км/ч. Скорость течения 3,9 км/ч. Найдите собственную скорость катера и его скорость по течению.

Answer 1

1) 11,3 км/ч + 3,9км/ч = 15,2км/ч -скорость катера
2) 15,2 км/ч + 3,9км/ч = 19,1 км/ч - скорость по течению

Answer 2

1)11,3+3,9=15,2 км/ч(скорость катера) 15,2+3,9=19,1 км/ч (по течению)

Answer 3

Calculation of Boat's Speed and Speed Relative to Current

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

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

Given: - Speed against the current: 11.3 km/h - Speed of the current: 3.9 km/h

Using the formula, we can calculate the boat's speed:

Boat's Speed = 11.3 km/h + 3.9 km/h = 15.2 km/h To find the speed of the boat relative to the current, we subtract the speed of the current from the boat's speed:

Speed of the Boat Relative to the Current = Boat's Speed - Speed of the Current

Speed of the Boat Relative to the Current = 15.2 km/h - 3.9 km/h = 11.3 km/h Therefore, the boat's speed is 15.2 km/h and its speed relative to the current is 11.3 km/h.
