Question

от двух пристаней одновременно навстречу друг другу вышли два катера.Скорость первого катера 27км/ч,а скорость второго катера 24 км/ч Через 4 часа расстояние между ними было 235 км.Чему равно расстояние между пристанями?

Answer 1

4*27=108км-проплыл первый катер

4*24=96км-проплыл второй катер

108+96+235=439км-расстояние между пристанями

Answer 2

Ответ:

Пошаговое объяснение:

S=27*4+24*4+235=108+96+235=439 км расстояние между пристанями

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 27 km/h, and the speed of the second boat is 24 km/h. After 4 hours, the distance between them is 235 km. We need to find the distance between the piers. #### Solution Let's assume that the distance between the piers is **x** km. After 4 hours, the first boat has traveled a distance of **27 km/h * 4 h = 108 km**. Similarly, the second boat has traveled a distance of **24 km/h * 4 h = 96 km**. The total distance covered by both boats after 4 hours is **108 km + 96 km = 204 km**. Since they are moving towards each other, the distance between them is decreasing by the sum of their speeds, which is **27 km/h + 24 km/h = 51 km/h**. To find the remaining distance between the piers, we can subtract the distance covered by both boats from the initial distance between them: **x - 204 km = 235 km** Simplifying the equation, we get: **x = 439 km** Therefore, the distance between the piers is **439 km**. #### Answer The distance between the piers is **439 km**.
