Question

От двух пристаней одновременно навстречу друг другу отошли 2 катера скорость первого катера 17 км/ч скорость другого 16 км/ч через сколько часов катера встретятся если расстояние между пристанями 132 км *Решите с пояснениями без иксов!*

Answer 1

1)17+16=33км/ч скорость сближения
2)132 : 33=4часа они встретятся

Answer 2

1) Узнаем скорость сближения.
17+16=33(км/ч) скорость сближения.
2) Узнаем через сколько времени встретятся катера.
132:33=4(ч)
Ответ: катера встретятся через 4 часа.

Answer 3

Problem Analysis

We have two boats that start from two different piers and move towards each other. The speed of the first boat is 17 km/h, and the speed of the second boat is 16 km/h. The distance between the piers is 132 km. We need to find out how many hours it will take for the boats to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed. We can calculate the time it takes for each boat to reach the meeting point and then find the total time.

Let's calculate the time it takes for the first boat to reach the meeting point: time1 = distance / speed1 = 132 km / 17 km/h.

Now, let's calculate the time it takes for the second boat to reach the meeting point: time2 = distance / speed2 = 132 km / 16 km/h.

Finally, we can find the total time it takes for the boats to meet by adding the individual times: total time = time1 + time2.

Let's calculate the values:

time1 = 132 km / 17 km/h = 7.7647 hours (rounded to 4 decimal places).

time2 = 132 km / 16 km/h = 8.25 hours.

total time = 7.7647 hours + 8.25 hours = 16.0147 hours (rounded to 4 decimal places).

Therefore, the boats will meet after approximately 16.0147 hours.

Answer

The boats will meet after approximately 16.0147 hours.

Explanation

The first boat will take approximately 7.7647 hours to reach the meeting point, while the second boat will take approximately 8.25 hours. The total time it takes for the boats to meet is the sum of these individual times, which is approximately 16.0147 hours.
