Question

Моторная лодка прошла 35 км по озеру, а затем 34 км по реке, что впадает в это озеро, за 2 ч. Найдите собственную скорость лодки, если скорость течения реки составляет 1 км / ч.

Answer 1

Скорость лодки будет составлять 100 км/ч

Answer 2

Calculating the Boat's Speed

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

First, let's calculate the total time taken for the boat to travel 35 km on the lake and 34 km on the river.

The time taken to travel 35 km on the lake can be calculated using the formula: time = distance / speed

The time taken to travel 34 km on the river can be calculated using the formula: time = distance / (speed of the boat + speed of the river)

We can then use these time values to find the speed of the boat.

Calculating Time on the Lake

The time taken to travel 35 km on the lake can be calculated using the formula: time = distance / speed

Given: - Distance on the lake = 35 km - Speed on the lake = boat's speed

Using the given information, we can calculate the time taken to travel 35 km on the lake.

Calculating Time on the River

The time taken to travel 34 km on the river can be calculated using the formula: time = distance / (speed of the boat + speed of the river)

Given: - Distance on the river = 34 km - Speed of the river = 1 km/h

Using the given information, we can calculate the time taken to travel 34 km on the river.

Finding the Boat's Speed

After calculating the time taken for both the lake and the river, we can use these values to find the speed of the boat.

Let's proceed with the calculations.
