Question

Катер за 2 часа по озеру и за 3 часа против течения реки проплывает такое же расстояние что из за 3 часа 24 минуты по течению реки. Найдите собственную скорость катера если скорость течения реки равна трем километров в час

Answer 1

2 умножить на 3 и 3 умножить на 3 потом  3*3-2*3= 3 , 24;3=8

Answer 2

Finding the Boat's Speed

To find the boat's speed, we can use the formula: speed = distance / time

First, let's calculate the boat's speed when traveling across the lake and against the river's current.

Speed Across the Lake

The boat travels the same distance in 2 hours across the lake.

Speed across the lake = distance / time = distance / 2

Speed Against the River's Current

The boat travels the same distance in 3 hours against the river's current.

Speed against the river's current = distance / time = distance / 3

Now, let's use the given information to solve for the boat's speed.

Calculating the Boat's Speed

The boat's speed when traveling across the lake is the same as the speed against the river's current. We can set up the equation:

distance / 2 = distance / 3 + 3/20

Where 3/20 represents the additional time taken when traveling against the river's current.

Solving for the Boat's Speed

By solving the equation, we can find the boat's speed.

distance / 2 = distance / 3 + 3/20

Let's solve for the boat's speed.
