Question

От двух пристаней расстояние между которыми 120 километров одновременно отошли навстречу друг другу два теплохода один из них шел со скоростью 22 км в час а другой со скоростью 18 км ч через сколько часов теплоходы встретились какое расстояние прошел до встречи каждый теплоход

Answer 1

1) 22 + 18 = 40 км/ч - скорость двух теплоходов вместе. 2) 120 : 40 = 3 ч - встретились теплоходы. 3) 22 х 3 = 66 км - прошел первый теплоход до встречи. 4) 120 - 66 = 54 км - прошел второй теплоход до встречи.

Answer 2

1)120:(22+18)=3 ч плыли теплоходы
2) 22 * 3 = 66 км проплыл 1-й теплоход
3)18* 3 = 54 км проплыл 2-й теплоход

Answer 3

Problem Analysis

We have two ships that start from two different ports and are moving towards each other. The distance between the ports is 120 kilometers. One ship is traveling at a speed of 22 km/h, while the other is traveling at a speed of 18 km/h. We need to determine 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.

Ship 1 is traveling at a speed of 22 km/h, so the time it will take for Ship 1 to meet Ship 2 can be calculated as follows:

time1 = distance / speed1 = 120 km / 22 km/h

Similarly, Ship 2 is traveling at a speed of 18 km/h, so the time it will take for Ship 2 to meet Ship 1 can be calculated as follows:

time2 = distance / speed2 = 120 km / 18 km/h

Now, let's calculate the values.

Calculation

Using the given values: - Distance between the ports: 120 kilometers - Speed of Ship 1: 22 km/h - Speed of Ship 2: 18 km/h

We can calculate the time it will take for the ships to meet:

time1 = 120 km / 22 km/h = 5.45 hours

time2 = 120 km / 18 km/h = 6.67 hours

Since the ships are moving towards each other, they will meet at the same time. Therefore, the ships will meet after approximately 5.45 hours.

To calculate the distance each ship has traveled before the meeting, we can use the formula: distance = speed * time.

For Ship 1: distance1 = speed1 * time1 = 22 km/h * 5.45 hours

For Ship 2: distance2 = speed2 * time2 = 18 km/h * 5.45 hours

Calculation

Using the calculated values: - Time for Ship 1 to meet Ship 2: 5.45 hours - Time for Ship 2 to meet Ship 1: 5.45 hours - Speed of Ship 1: 22 km/h - Speed of Ship 2: 18 km/h

We can calculate the distance each ship has traveled before the meeting:

distance1 = 22 km/h * 5.45 hours = 119.9 kilometers

distance2 = 18 km/h * 5.45 hours = 98.1 kilometers

Therefore, Ship 1 will have traveled approximately 119.9 kilometers before the meeting, and Ship 2 will have traveled approximately 98.1 kilometers before the meeting.

Answer

The ships will meet after approximately 5.45 hours. Ship 1 will have traveled approximately 119.9 kilometers, and Ship 2 will have traveled approximately 98.1 kilometers before the meeting.
