Question

Два пограничных катера плывут друг другу навстречу.Скорость первого 32 км/ч ,а скорость второго 40 км/ч .Сейчас между ними 360 км . Какое расстояние будем между ними через 2 часа

Answer 1

1)32х2=64(км)-проплывет 1 катер через 2ч
2)40х2=80(км)-проплывет 2 катер через 2ч
3)64+80=144(км)-проплывут 1 и 2 катера через 2ч
4)360-144=216(км)
Ответ: расстояние между ними через 2 часа-216км.

Answer 2

1) 32 + 40 = 72 км/ч - скорость сбл.
2) 72 × 2 = 144 км - расстояние, пройденное за 2 часа
3) 360 - 144 = 216 км - ответ

Answer 3

Problem Statement

Два пограничных катера плывут друг другу навстречу. Скорость первого 32 км/ч, а скорость второго 40 км/ч. Сейчас между ними 360 км. Какое расстояние будет между ними через 2 часа?

Solution

To find the distance between the two boats after 2 hours, we need to calculate the total distance covered by both boats in that time.

Let's start by calculating the distance covered by the first boat in 2 hours. The speed of the first boat is 32 km/h, so in 2 hours, it will cover a distance of 32 km/h * 2 h = 64 km.

Next, let's calculate the distance covered by the second boat in 2 hours. The speed of the second boat is 40 km/h, so in 2 hours, it will cover a distance of 40 km/h * 2 h = 80 km.

Now, let's calculate the new distance between the two boats. Currently, there is a distance of 360 km between them. After 2 hours, the first boat will have covered 64 km and the second boat will have covered 80 km. Therefore, the new distance between them will be 360 km - (64 km + 80 km) = 216 km.

So, the distance between the two boats after 2 hours will be 216 km.
