Question

Теплоход прошел за первый день 3/10 всего пути, а во второй день – на 1/5 части меньше, чем в первый день. Какую часть пути теплоход прошел за два дня? даю 30 баллов​

Answer 1

Ответ:

2/5 пути прошел теплоход за 2 дня

Пошаговое объяснение:

1) 3/10-1/5=3/10-2/10=1/10 пути прошел теплоход во 2й день

2) 3/10+1/10=4/10 или 2/5 пути прошел теплоход за 2 дня

Answer 2

Calculation of the Distance Traveled by the Ship

To determine the fraction of the total distance traveled by the ship in two days, we need to calculate the distances traveled on the first and second days separately.

Let's assume that the total distance traveled by the ship is represented by x.

On the first day, the ship traveled 3/10 of the total distance. Therefore, the distance traveled on the first day can be calculated as (3/10) * x.

On the second day, the ship traveled 1/5 less than the distance traveled on the first day. This means the distance traveled on the second day can be calculated as (1 - 1/5) * (3/10) * x.

To find the total distance traveled in two days, we need to add the distances traveled on the first and second days:

Total distance traveled = (3/10) * x + (1 - 1/5) * (3/10) * x

Simplifying the equation:

Total distance traveled = (3/10) * x + (4/5) * (3/10) * x

Factoring out (3/10) * x:

Total distance traveled = (3/10) * x * (1 + 4/5)

Simplifying further:

Total distance traveled = (3/10) * x * (9/5)

Multiplying the fractions:

Total distance traveled = (27/50) * x

Therefore, the ship traveled 27/50 of the total distance in two days.

Answer:

The ship traveled 27/50 of the total distance in two days.
