Question

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

Answer 1

18+22=40 скорость сближения
120÷40=3ч встретились
22×3=66км прошел первый теплоход
18×3=54км прошел второй теплоход

Answer 2

Calculating the Meeting Time and Distance Traveled by Each Ship

To calculate the time it takes for the two ships to meet and the distance each ship has traveled, we can use the formula:

time = distance / speed

First, let's calculate the time it takes for the two ships to meet:

The total distance between the two ships is 120 km. One ship is traveling at a speed of 22 km/h, and the other is traveling at a speed of 18 km/h.

Using the formula, we can calculate the time it takes for the two ships to meet: - For the first ship: time = 120 km / 22 km/h - For the second ship: time = 120 km / 18 km/h

Let's calculate the time it takes for the two ships to meet using the given speeds.

Time taken for the first ship to meet: 120 km / 22 km/h = 5.45 hours

Time taken for the second ship to meet: 120 km / 18 km/h = 6.67 hours

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

Distance traveled by the first ship: 22 km/h * 5.45 hours = 119.9 km

Distance traveled by the second ship: 18 km/h * 6.67 hours = 120.06 km

So, the two ships will meet after approximately 5.45 hours, and the first ship will have traveled approximately 119.9 km, while the second ship will have traveled approximately 120.06 km.

This calculation assumes constant speeds for both ships and a direct path between the two ports.
