Question

Лодка имеющая собственную скорость 6 км ч проплыл 3 часа по течению реки и 5 часов против течения реки Какое расстояние проплыл лодки если скорость течения реки равна 2 км ч

Answer 1

6+2=8км/час скорость по течению
6-2=4км/час скорость против течения
8*3+4*5=44км всего проплыла лодка

Answer 2

Problem Analysis

We are given the following information: - The boat has a speed of 6 km/h. - The boat traveled for 3 hours with the current. - The boat traveled for 5 hours against the current. - The speed of the current is 2 km/h.

We need to find the distance traveled by the boat.

Solution

To find the distance traveled by the boat, we can use the formula:

Distance = Speed × Time

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

1. Distance traveled with the current: - Speed of the boat: 6 km/h - Time: 3 hours - Speed of the current: 2 km/h

Using the formula, the distance traveled with the current is: Distance with current = (Speed of the boat + Speed of the current) × Time Distance with current = (6 km/h + 2 km/h) × 3 hours Distance with current = 8 km/h × 3 hours Distance with current = 24 km

2. Distance traveled against the current: - Speed of the boat: 6 km/h - Time: 5 hours - Speed of the current: 2 km/h

Using the formula, the distance traveled against the current is: Distance against current = (Speed of the boat - Speed of the current) × Time Distance against current = (6 km/h - 2 km/h) × 5 hours Distance against current = 4 km/h × 5 hours Distance against current = 20 km

Now, to find the total distance traveled by the boat, we can add the distance traveled with the current and the distance traveled against the current: Total distance = Distance with current + Distance against current Total distance = 24 km + 20 km Total distance = 44 km

Therefore, the boat traveled a total distance of 44 km.

Answer

The boat traveled a total distance of 44 km.
