Question

От двух пристаней, расстояние между которыми 350км.,в 11ч. отправились навстречу друг другу два теплохода. Средняя скорость первого 32км/ч. Средняя скорость второго- 38км/ч. В какое время теплоходы встретятся?

Answer 1

32 км/ч + 38км/ч = 70 км/ч  - средняя скорость обоих теплоходов350 км : 70 км/ч = 5 ч  - потребуется теплоходам, чтоб преодолеть 350 км 11 ч + 5 ч = 16 ч - теплоходы встретятся в 16 часов.Ответ: В 16 ч.

Answer 2

1) 32+38=70 км/час скорость сближения теплоходов                                          2) 350:70=5 (через 5 часов теплоходы встретились)                                           3) 11+5=16 (в 16 часов произошла встреча)                                                          Ответ: Теплоходы встретились в 16 часов

Answer 3

Problem Analysis

We have two steamboats that start from two different ports and are traveling towards each other. The distance between the ports is 350 km. The first steamboat has an average speed of 32 km/h, while the second steamboat has an average speed of 38 km/h. We need to determine the time it will take for the steamboats to meet.

Solution

To find the time it takes for the steamboats to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two steamboats. Let's calculate the time it takes for the steamboats to meet.

Calculation

The distance between the two ports is 350 km. The first steamboat has an average speed of 32 km/h, and the second steamboat has an average speed of 38 km/h.

The relative speed of the two steamboats is:

Relative Speed = Speed of Steamboat 1 + Speed of Steamboat 2

Relative Speed = 32 km/h + 38 km/h = 70 km/h

Now, we can calculate the time it takes for the steamboats to meet:

Time = Distance / Relative Speed

Time = 350 km / 70 km/h = 5 hours

Therefore, the steamboats will meet in 5 hours.

Answer

The steamboats will meet in 5 hours.

Note: The answer is based on the given information and assumes that the steamboats travel at a constant speed throughout the journey.
