Question

Ледокол 3 дня пробивал себе путь во льдах. В первый день он проплыл 2/5 всего пути, во второй день — 5/8 оставшегося пути, а в третий день — оставшиеся 90 км. Какой путь проплыл ледокол за 3 дня пути? Сколько километров он проплыл в первый и во второй день?

Answer 1

1) 90:3=30км 1 часть пути
2) 30*50=150км во 2 день
3) 150+90=240км за 2 и 3 день

Answer 2

Calculating the Icebreaker's Journey

To calculate the distance the icebreaker traveled over the three days, we can use the information provided.

Day 1: The icebreaker traveled 2/5 of the total distance.

Day 2: It traveled 5/8 of the remaining distance.

Day 3: It traveled the remaining 90 km.

Let's calculate the total distance traveled and the distance covered on the first and second days.

Calculations:

1. Day 1: - Distance traveled: 2/5 of the total distance. - Let's represent the total distance as D. - Distance traveled on the first day = (2/5) * D.

2. Day 2: - Remaining distance after Day 1 = D - (2/5) * D = (3/5) * D. - Distance traveled on the second day: 5/8 of the remaining distance. - Distance traveled on the second day = (5/8) * (3/5) * D.

3. Day 3: - Remaining distance after Day 2 = (3/5) * D - (5/8) * (3/5) * D = 90 km.

Let's calculate the distances.

Calculation Results:

1. Day 1: - Distance traveled on the first day = (2/5) * D.

2. Day 2: - Distance traveled on the second day = (5/8) * (3/5) * D.

3. Day 3: - Remaining distance after Day 2 = (3/5) * D - (5/8) * (3/5) * D = 90 km.

Now, let's solve for the total distance traveled and the distance covered on the first and second days.

Solution:

Given that the remaining distance after Day 2 is 90 km, we can solve for the total distance and the distances covered on the first and second days.

Using the information provided, we can solve for the total distance and the distances covered on the first and second days.
