Question

Катер проплыл против течения 2,9 ч и по течению 4,8 ч. Собственая скорость катера ровна 19, 4 км/ч, а скорость течения 1,6 км/ч. Какое расстояние проплыл катер по течению и против течения? пожалуйста очень надо срочно

Answer 1

Ответ:

1)19,4-17,8=1,6 км/ч (скорость теч. Реки)

2)19,4+1,6=21км/ч

Ответ: скорость катера по течению реки 21 км/ч

Answer 3

Calculation of Distance Traveled by the Boat

To calculate the distance traveled by the boat both against and with the current, we can use the formula:

Distance = Speed x Time

Given the following information: - Speed of the boat: 19.4 km/h - Speed of the current: 1.6 km/h - Time traveled against the current: 2.9 hours - Time traveled with the current: 4.8 hours

Let's calculate the distance traveled by the boat both against and with the current.

1. Distance traveled against the current: - Speed of the boat against the current = Speed of the boat - Speed of the current = 19.4 km/h - 1.6 km/h = 17.8 km/h - Distance traveled against the current = Speed against the current x Time against the current = 17.8 km/h x 2.9 hours = 51.62 km

2. Distance traveled with the current: - Speed of the boat with the current = Speed of the boat + Speed of the current = 19.4 km/h + 1.6 km/h = 21 km/h - Distance traveled with the current = Speed with the current x Time with the current = 21 km/h x 4.8 hours = 100.8 km

Therefore, the boat traveled approximately 51.62 km against the current and 100.8 km with the current.

Please note that the calculations provided are based on the given information and assumptions.
