Question

Из двух портов, расстояние между которыми 420 миль, вышли одновременно навстречу друг другу два парусника. Скорость одного парусника 16 миль/ч. Найди скорость другого парусника, если они встретились через 12 часов

Answer 1

420:12=35 (миль/ч) скорость сближения или сумма скоростей
35-16=19 (миль/ч)
Ответ: скорость другого 19 миль в час

Answer 2

1)16*12=192(миль)1 парусник

Answer 3

Problem Analysis

We have two sailboats that set sail from two ports simultaneously and are heading towards each other. The distance between the ports is 420 miles. We know the speed of one sailboat, which is 16 miles per hour. We need to find the speed of the other sailboat given that they meet after 12 hours.

Solution

To find the speed of the second sailboat, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the second sailboat using this formula.

Calculation

The distance between the two ports is 420 miles, and they meet after 12 hours.

Using the formula, we can calculate the speed of the second sailboat:

Speed of the second sailboat = Distance / Time

Speed of the second sailboat = 420 miles / 12 hours

Speed of the second sailboat = 35 miles per hour

Therefore, the speed of the second sailboat is 35 miles per hour.

Answer

The speed of the second sailboat is 35 miles per hour.
