Question

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

Answer 1

1) 32+38=70 км/ч скорость сближения
2) 350 : 70= 5 часов - время в пути
3) 11+5=16 часов - время встречи

Answer 2

Problem Analysis

We have two ships traveling towards each other from two different ports. The distance between the ports is 350 km. 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 it takes 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 two ports is 350 km. The speed of the first ship is 32 km/h. The speed of the second ship is 38 km/h.

The relative speed of the two ships 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

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

Therefore, the ships will meet in 5 hours.

Answer

The two ships will meet in 5 hours.
