Question

турист пройшов 9 км за 3 години. За 1 годину він пройшов 2 цілих 7,10 км,а за 2 на 9,10 більше,ніж за 1. Яку відстань пройшов турист за 3 годину?​

Answer 1

Ответ:

в третий год он прошел

$2 \frac{7}{10}$км.

Пошаговое объяснение:

Найдём сколько он прошел во второй год:

$2 \frac{7}{10} + \frac{9}{10} = 2 \frac{16}{10} = 3 \frac{6}{10} = 3 \frac{3}{5}$

Теперь сложим и минусуем от общего:

$9 - (2 \frac{7}{10} - 3 \frac{6}{10} ) = 9- 5 \frac{13}{10} = 9 - 6 \frac{3}{10} = 2 \frac{10 - 3}{10} = 2 \frac{7}{10}$

Answer 2

Calculating the Distance Traveled by the Tourist

To calculate the distance the tourist traveled in 3 hours, we can use the information provided about the distances covered in 1 hour and 2 hours.

Given: - The tourist walked 9 km in 3 hours. - In 1 hour, the tourist walked 2 whole kilometers and 7.10 km. - In 2 hours, the tourist walked 9.10 km more than in 1 hour.

Let's calculate the distance the tourist traveled in 3 hours step by step.

1. Distance Covered in 1 Hour: - The tourist walked 2 whole kilometers and 7.10 km in 1 hour.

2. Distance Covered in 2 Hours: - The tourist walked 9.10 km more than in 1 hour, which means the distance covered in 2 hours is the sum of the distance covered in 1 hour plus 9.10 km.

3. Distance Covered in 3 Hours: - Finally, to find the distance covered in 3 hours, we add the distance covered in 2 hours to the distance covered in 1 hour.

Let's calculate the distance covered in each time period.

Calculation

1. Distance Covered in 1 Hour: - 2 km + 7.10 km = 9.10 km

2. Distance Covered in 2 Hours: - 9.10 km + 9.10 km = 18.20 km

3. Distance Covered in 3 Hours: - 18.20 km + 9 km = 27.20 km

Therefore, the tourist covered a distance of 27.20 km in 3 hours.
