Question

От двух пристаней, расстояние между которыми 35 км. в 11 ч отправились навстречу друг к другу два теплохода. Средняя скорость первого 32 км/ч.а второго 38 км/ч. В какое время теплоходы встретятся?

Answer 1

32+38=70 (км/ч) скорость сближения
350/70=5 (ч) время в пути
11+5=16 часов теплоходы встретятся

Answer 2

1)38+32= 70 (км/ч) - общая скорость
2)350:70=5(ч) -общее время
3)11+5=16 (ч)
Ответ: в 16 часов

Answer 3

Problem Analysis

We have two ships that are traveling towards each other from two different ports. The distance between the ports is 35 km. The first ship has an average speed of 32 km/h, and the second ship has an average speed of 38 km/h. We need to determine the time it will take for the ships to meet.

Solution

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

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two ships.

Let's calculate the time it takes for the ships to meet.

Calculation

The distance between the ports is 35 km.

The speed of the first ship is 32 km/h.

The speed of the second ship is 38 km/h.

The relative speed is the sum of the speeds of the two ships: 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 = 35 km / 70 km/h = 0.5 hours

Therefore, the ships will meet in 0.5 hours, or 30 minutes.

Answer

The ships will meet in 0.5 hours or 30 minutes.
