Question

От двух пристаней расстояние меду которыми 120 км одновременно отошли навстречу друг к другу два теплохода. Один из них шёл со средней скоростью 22 км/ч другой-18 км/ч. Через сколько часов теплоходы встретились? Какое расстояние прошёл до встречи каждый теплоход.

Answer 1

|  1) 22 + 18 = 40 (км/ч) - скорость сближения
|  2) 120 : 40 = 3 (часа) - до встречи
|  3) 22 x 3 = 66 (км) - прошёл первый теплоход
|  4) 18 x 3 = 54 (км) - прошёл второй теплоход
|  Ответ: Первый теплоход прошёл 66 км. Второй теплоход прошёл                                                                                                                  54  км.

Answer 2

Problem Analysis

We are given that two ships are moving towards each other from two different ports. The distance between the ports is 120 km. The first ship is traveling at a speed of 22 km/h, and the second ship is traveling at a speed of 18 km/h. We need to find out how many hours it will take for the ships to meet and the distance each ship has traveled before the meeting.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for the ships to meet:

For the first ship: Time1 = Distance / Speed1 = 120 km / 22 km/h

For the second ship: Time2 = Distance / Speed2 = 120 km / 18 km/h

Now, let's calculate the distance each ship has traveled before the meeting:

For the first ship: Distance1 = Speed1 * Time1 = 22 km/h * (120 km / 22 km/h)

For the second ship: Distance2 = Speed2 * Time2 = 18 km/h * (120 km / 18 km/h)

Let's calculate the values:

Time1 = 120 km / 22 km/h = 5.45 hours

Time2 = 120 km / 18 km/h = 6.67 hours

Distance1 = 22 km/h * (120 km / 22 km/h) = 120 km

Distance2 = 18 km/h * (120 km / 18 km/h) = 120 km

Therefore, it will take approximately 5.45 hours for the ships to meet, and each ship will travel a distance of 120 km before the meeting.

Please note that the above calculations are approximate and may vary slightly depending on the exact values used.

Answer

The ships will meet approximately after 5.45 hours. Each ship will travel a distance of 120 km before the meeting.
