Question

Путешественник в первый день прошел 15 % всего пути, во второй день две седьмых всего пути. Какой путь был пройден им во второй день, если в первый он прошел21 км?

Answer 1

1) 15%=0,15
Составим уравнение ( найдём длину всего пути)
0,15*Х=21
Х=21:0,15
Х=140км
2) 140*2/7=140/1*2/7=20*2=40км (прошёл во второй день)

Answer 2

Solution:

To find out the distance traveled on the second day, we can use the information provided. On the first day, the traveler covered 15% of the total distance, which is 21 km. On the second day, the traveler covered two sevenths (2/7) of the total distance.

Let's calculate the total distance and then find out the distance covered on the second day.

1. Total Distance Calculation: - On the first day, the traveler covered 15% of the total distance, which is 21 km. - We can use this information to calculate the total distance.

The total distance can be calculated using the formula: \[ \text{Total Distance} = \frac{21}{0.15} \]

\[ \text{Total Distance} = 140 \]

Therefore, the total distance is 140 km.

2. Distance Covered on the Second Day: - On the second day, the traveler covered two sevenths (2/7) of the total distance. - We can calculate the distance covered on the second day using this information.

The distance covered on the second day can be calculated using the formula: \[ \text{Distance on Second Day} = \frac{2}{7} \times 140 \]

\[ \text{Distance on Second Day} = 40 \]

Therefore, the traveler covered 40 km on the second day.

So, based on the given information, the traveler covered 40 km on the second day.
