Question

От двух пристаней одновременно навстречу друг другу отправились два теплохода.Расстояние между пристанями 474 км.Скорость одного теплохода 42км/ч.Какой путь прошёл каждый теплоход до встречи,если они встретились через 6ч?

Answer 1

474/6=79км/ч скорость сближения

79-42=37км/ч скорость второго теплохода

42*6=252км прошел первый

37*6=222км прошел второй   или  474-252=222км

Answer 2

1)474:6=79км/ч-скорость сближения. 2)79-42=37км/ч-скорость второго теплохода. 3)42*6=252км-прошёл первый теплоход. 4)37*6=222км-прошёл второй теплоход.

Answer 3

Problem Analysis

We have two steamboats traveling towards each other from two different piers. The distance between the piers is 474 km, and the speed of one steamboat is 42 km/h. We need to calculate the distance each steamboat traveled before they met, given that they met after 6 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the distance traveled by the first steamboat is x km. Since the total distance between the piers is 474 km, the distance traveled by the second steamboat would be 474 - x km.

We know that the speed of the first steamboat is 42 km/h, and they met after 6 hours. Therefore, the distance traveled by the first steamboat is 42 × 6 = 252 km.

Using this information, we can set up the following equation:

x + (474 - x) = 252

Simplifying the equation, we get:

474 = 252 + x

Solving for x, we find:

x = 474 - 252 = 222 km

Therefore, the first steamboat traveled 222 km, and the second steamboat traveled 474 - 222 = 252 km before they met.

Answer

Each steamboat traveled the following distances before they met: - The first steamboat traveled 222 km. - The second steamboat traveled 252 km.
