Question

Скорость катера 18,4 км час, Скорость течения равно на 0,15 скоростя катера Если катер поплывёт против течения то во скольких километрах он окажется через 3 часа ?

Answer 1

Calculation of the Distance Traveled by the Boat

To calculate the distance the boat will travel in 3 hours against the current, we need to consider the boat's speed and the speed of the current.

Given: - Boat speed: 18.4 km/h - Current speed: 0.15 times the boat's speed

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

Effective speed of the boat against the current = Boat speed - (Current speed)

Let's calculate the effective speed of the boat against the current:

Effective speed of the boat against the current = 18.4 km/h - (0.15 * 18.4 km/h)

Now, we can calculate the distance the boat will travel in 3 hours against the current:

Distance = Speed * Time

Distance = (Effective speed of the boat against the current) * 3 hours

Let's calculate the distance:

Distance = (18.4 km/h - (0.15 * 18.4 km/h)) * 3 hours

Distance = (18.4 km/h - 2.76 km/h) * 3 hours

Distance = 15.64 km/h * 3 hours

Distance = 46.92 km

Therefore, if the boat travels against the current, it will be approximately 46.92 kilometers away after 3 hours.
