Question

Корабли движутся по курсу со скоростью 10 узлов в час. Какое расстояние пройдут корабли за время игры (45 мин.)? При попутном ветре . скорость 0,5 км/ч (ответ дать в километрах, округлив до десятых) Справка: 1 морской узел – скорость, равная 1 морской миле в час. 1 морская миля в час = 1,85 км/ч.

Answer 1

Пусть скорость кораблей - v, скорость ветра - u
Тогда l=t(v+u)
l=0.75(18.5+0.5)=14.25(км)=14.3(км)
Ответ: ~14.3 км

Answer 2

Calculating Distance Traveled by Ships

To calculate the distance traveled by the ships, we can use the formula:

Distance = Speed × Time

Given: - Speed of the ships = 10 knots - Time = 45 minutes - Wind speed = 0.5 km/h

First, let's convert the ship's speed from knots to km/h using the conversion factor provided: 1 knot = 1.85 km/h

So, the speed of the ships in km/h = 10 knots × 1.85 km/h/knot = 18.5 km/h

Now, we can calculate the distance traveled by the ships in 45 minutes.

Calculating Distance Traveled in Kilometers

Using the formula Distance = Speed × Time, and converting time to hours: - Time = 45 minutes = 45/60 hours = 0.75 hours

Distance = 18.5 km/h × 0.75 hours = 13.875 km

So, the ships will travel approximately 13.9 kilometers in 45 minutes with a wind speed of 0.5 km/h.

This calculation assumes a constant speed and direction for the ships and the wind.
