Question

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

Answer 1

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

Answer 2

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 traveled by each steamboat before they meet, given that they meet after 6 hours.

Solution

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

Let's calculate the distance traveled by each steamboat before they meet.

Calculation

The speed of one steamboat is 42 km/h. Therefore, in 6 hours, it will travel a distance of: distance = speed × time = 42 km/h × 6 h = 252 km.

Since the two steamboats are traveling towards each other, the total distance traveled by both steamboats before they meet is equal to the distance between the piers, which is 474 km.

Let's calculate the distance traveled by the second steamboat: distance traveled by the second steamboat = total distance - distance traveled by the first steamboat = 474 km - 252 km = 222 km.

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

Answer

The first steamboat traveled 252 km, and the second steamboat traveled 222 km before they met.
