Question

Подводная лодка шла трое суток. В первые сутки подводная лодка прошла 4/15 намеченного пути, во вторые 0,3 всего пути. Сколько километров прошла лодка в третий день, если за 3 дня она прошла 3000 километров. Помогите пожалуйста, очень надо.

Answer 1

1 сутки------  3000*4/15 =800 ( км)

2 -ые сутки-- 3000*0,3 =900(км )

3 -и сутки -----3000 - (800+900) = 1300 (км )

Answer 2

Calculation of Distance Traveled by the Submarine

To calculate the distance traveled by the submarine on the third day, we need to determine the distances covered on the first and second days.

Let's denote the total distance traveled by the submarine as D (which is given as 3000 kilometers) and the distance covered on the third day as D3.

According to the information provided, the submarine covered 4/15 of the total distance on the first day and 0.3 of the total distance on the second day.

We can set up the following equations:

- Distance covered on the first day: D1 = (4/15) * D - Distance covered on the second day: D2 = 0.3 * D

To find the distance covered on the third day, we subtract the distances covered on the first and second days from the total distance:

- Distance covered on the third day: D3 = D - D1 - D2

Let's calculate the values:

- Distance covered on the first day: D1 = (4/15) * 3000 = 800 kilometers - Distance covered on the second day: D2 = 0.3 * 3000 = 900 kilometers - Distance covered on the third day: D3 = 3000 - 800 - 900 = 1300 kilometers

Therefore, the submarine traveled 1300 kilometers on the third day.
