Question

От 2 пристаней расстояние между которыми 350 километров в 11:00 отправились навстречу друг другу два теплохода средняя скорость первого 32 километра в час средняя скорость 38 км в час

Answer 1

32+38=70км скорость сьлишения
350÷70=5 часов
11+5= 16 часов они встретятся

Answer 2

Problem Statement

Two ships set sail from two different ports that are 350 kilometers apart at 11:00. The first ship has an average speed of 32 kilometers per hour, while the second ship has an average speed of 38 kilometers per hour. What time will they meet?

Solution

To find the time when the two ships will meet, we can calculate the time it takes for each ship to cover the distance between them. Since they are moving towards each other, their combined speed will be the sum of their individual speeds.

Let's calculate the time it takes for the first ship to cover the distance: Distance = 350 kilometers Speed of the first ship = 32 kilometers per hour Time taken by the first ship = Distance / Speed = 350 / 32 = 10.9375 hours

Now, let's calculate the time it takes for the second ship to cover the distance: Distance = 350 kilometers Speed of the second ship = 38 kilometers per hour Time taken by the second ship = Distance / Speed = 350 / 38 = 9.2105 hours

Since both ships started at 11:00, we need to add the time taken by the second ship to the starting time to find the meeting time: Meeting time = Starting time + Time taken by the second ship

Let's calculate the meeting time: Starting time = 11:00 Time taken by the second ship = 9.2105 hours

To add the time taken by the second ship to the starting time, we need to convert the time taken by the second ship to minutes and add it to the starting time in minutes.

Time taken by the second ship in minutes = Time taken by the second ship * 60 = 9.2105 * 60 = 552.63 minutes

Now, let's add the time taken by the second ship to the starting time: Meeting time in minutes = Starting time in minutes + Time taken by the second ship in minutes

Since the starting time is 11:00, which is equivalent to 660 minutes, we can calculate the meeting time as follows: Meeting time in minutes = 660 + 552.63 = 1212.63 minutes

To convert the meeting time back to hours and minutes, we divide the meeting time in minutes by 60 to get the hours and take the remainder as the minutes.

Meeting time in hours = Meeting time in minutes / 60 = 1212.63 / 60 = 20.21 hours

Since the meeting time is 20.21 hours, we can convert it to hours and minutes as follows: Meeting time = 20 hours and 0.21 * 60 = 20 hours and 12.6 minutes

Therefore, the two ships will meet at approximately 20:12.

Note: The above calculations assume that the ships maintain a constant speed throughout the journey and do not encounter any delays or changes in speed.

Answer

The two ships will meet at approximately 20:12.
