Question

От двух пристаней расстояние между которыми 350км в 11 ч отправились навстречу друг другу два теплохода скорость первого 32км/ч скорость второго 38 км/ч в какое аремя теплоходы встретятся?

Answer 1

32 км/час+38 км/час=70 км/час (скорость сближения)
350 км:70 км/час=5 час (пройдут до встречи) (t=S:V)
11.00+5.00=16.00 (в 16 часов ровно они встретятся)
Ответ: теплоходы встретятся в 4 часа дня

Answer 2

1)32+38=70
2)350/70=5
3)11+5=16

Answer 3

Problem Analysis

We are given that two ships are traveling towards each other from two ports that are 350 km apart. The first ship has a speed of 32 km/h, and the second ship has a speed of 38 km/h. We need to determine the time at which the two ships will meet.

Solution

To find the time at which the two ships will meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed of the two ships is the sum of their individual speeds, as they are traveling towards each other. Let's calculate the time it takes for the ships to meet.

Calculation

The distance between the two ports is 350 km, and the relative speed of the two ships is the sum of their speeds, which is 32 km/h + 38 km/h = 70 km/h.

Using the formula, we can calculate the time it takes for the ships to meet:

Time = Distance / Relative Speed = 350 km / 70 km/h = 5 hours

Therefore, the two ships will meet after 5 hours.

Answer

The two ships will meet in 5 hours.

Explanation

When two objects are moving towards each other, their relative speed is the sum of their individual speeds. In this case, the relative speed of the two ships is 70 km/h. By dividing the distance between the two ports (350 km) by the relative speed (70 km/h), we can determine the time it takes for the ships to meet, which is 5 hours.
