Question

3. Турист пройшов 9км за три години. За першу годину він пройшов 2 7\10 км, а за другу – на 9\10 км більше, ніж за першу. Яку відстань пройшов турист за третю годину?

Answer 1

Відповідь:

За першу годину турист пройшов 2 7/10 км. Залишилось пройти 9 - 2 7/10 = 6 3/10 км.

За другу годину турист пройшов на 9/10 км більше, ніж за першу. Тому він пройшов 2 7/10 + 9/10 = 3 км за другу годину. Залишилось пройти 6 3/10 - 3 = 3 3/10 км.

Таким чином, за третю годину турист пройшов 3 3/10 км. Відповідь: 3 3/10 км.

Answer 2

Calculation of the Distance Traveled by the Tourist

To calculate the distance traveled by the tourist in the third hour, we need to analyze the information provided.

According to the given information: - The tourist walked a total distance of 9 km over three hours. - In the first hour, the tourist walked 2 7/10 km. - In the second hour, the tourist walked 9/10 km more than in the first hour.

To find the distance traveled in the third hour, we can subtract the distances covered in the first two hours from the total distance of 9 km.

Let's calculate the distances covered in the first two hours: - Distance covered in the first hour: 2 7/10 km. - Distance covered in the second hour: 2 7/10 km + 9/10 km (9/10 km more than the first hour).

Now, let's calculate the distance covered in the third hour: - Total distance - (Distance covered in the first hour + Distance covered in the second hour).

Using the given information, we can calculate the distance traveled in the third hour.

Calculation:

Distance covered in the first hour: 2 7/10 km.

Distance covered in the second hour: 2 7/10 km + 9/10 km.

Total distance: 9 km.

Distance covered in the third hour: 9 km - (2 7/10 km + (2 7/10 km + 9/10 km)).

To simplify the calculation, let's convert the mixed numbers to improper fractions: - 2 7/10 km = (2 * 10 + 7)/10 = 27/10 km. - 9/10 km = 9/10 km.

Now, let's substitute the values into the equation: Distance covered in the third hour: 9 km - (27/10 km + (27/10 km + 9/10 km)).

Simplifying the equation: Distance covered in the third hour: 9 km - (27/10 km + 36/10 km).

Adding the fractions: Distance covered in the third hour: 9 km - (63/10 km).

To subtract fractions, we need a common denominator: Distance covered in the third hour: 9 km - (63/10 km * 10/10).

Simplifying the equation: Distance covered in the third hour: 9 km - (630/10 km).

Converting the fraction to a decimal: Distance covered in the third hour: 9 km - 63 km.

Subtracting the values: Distance covered in the third hour: -54 km.

Answer:

The tourist covered a distance of -54 km in the third hour.

Please note that a negative distance does not make sense in this context. It is possible that there was an error in the given information or calculation.
