Question

Скорость лодки в стоячей воде 1,5 м/с. Каково расстояние (км) между поселками по реке, если лодка против течения реки проходит это расстояние за 1,5 часа, а по течению за 0,5 часа? Ответ округлите до десятых СРОЧНО!!!!!!!

Answer 1

60*1,5=90

60*90=5,400

5,400:1,5=3,600

3,600=0,00025( в десятых)

Answer 2

Calculation of Distance between Villages

To calculate the distance between the villages along the river, we need to consider the speed of the boat and the time it takes to travel both upstream and downstream.

Given: - Speed of the boat in still water: 1.5 m/s - Time taken to travel the distance upstream: 1.5 hours - Time taken to travel the distance downstream: 0.5 hours

To find the distance between the villages, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled upstream and downstream separately.

# Distance Traveled Upstream

When the boat is traveling upstream, it is moving against the current of the river. This means that the effective speed of the boat is reduced by the speed of the current.

Let's assume the speed of the current is x m/s.

The effective speed of the boat when traveling upstream is then (1.5 - x) m/s.

Using the formula, we can calculate the distance traveled upstream:

Distance upstream = (1.5 - x) m/s × 1.5 hours

# Distance Traveled Downstream

When the boat is traveling downstream, it is moving with the current of the river. This means that the effective speed of the boat is increased by the speed of the current.

Let's assume the speed of the current is y m/s.

The effective speed of the boat when traveling downstream is then (1.5 + y) m/s.

Using the formula, we can calculate the distance traveled downstream:

Distance downstream = (1.5 + y) m/s × 0.5 hours

# Finding the Distance between Villages

The total distance between the villages is the sum of the distances traveled upstream and downstream:

Total distance = Distance upstream + Distance downstream

To find the values of x and y, we need additional information or assumptions about the speed of the current. Unfortunately, the provided search results do not contain the necessary information to determine the values of x and y.

Therefore, without knowing the speed of the current, we cannot calculate the exact distance between the villages.
