Question

В первый час мотоциклист проехал 25% всего пути, во второй час 0,3, а в третий - остальные 35 км. Какое расстояние проехал мотоциклист за эти 3 часа !

Answer 1

1) 0,25 + 0,3 = 0,55 - часть пути, которую проехал мотоциклист за два часа
2) 1 - 0,55 = 0,45 - оставшаяся часть пути - это 35 км
3) 35 : 0,45 = 3500 / 45 = 700/9 = 77, 7/9 км - весь путь (смешанное число: семь целых и семь девятых)

Answer 2

Calculation of the Distance Traveled by the Motorcyclist

To calculate the distance traveled by the motorcyclist in the given scenario, we need to add up the distances covered in each hour.

1. In the first hour, the motorcyclist traveled 25% of the total distance. 2. In the second hour, the motorcyclist traveled 0.3 (or 30%) of the total distance. 3. In the third hour, the motorcyclist traveled the remaining 35 km.

Let's calculate the distance step by step:

1. First hour: 25% of the total distance. 2. Second hour: 30% of the total distance. 3. Third hour: 35 km.

To find the total distance, we need to add up these three distances.

Calculation:

1. First hour: 25% of the total distance. - Let's assume the total distance is D. - The distance covered in the first hour is 25% of D, which can be written as 0.25D.

2. Second hour: 30% of the total distance. - The distance covered in the second hour is 30% of D, which can be written as 0.3D.

3. Third hour: 35 km. - The distance covered in the third hour is 35 km.

Now, let's add up these distances to find the total distance traveled by the motorcyclist:

Total distance = Distance in the first hour + Distance in the second hour + Distance in the third hour

Total distance = 0.25D + 0.3D + 35 km

To find the value of D, we need more information or an equation. Unfortunately, the given information is not sufficient to calculate the exact distance traveled by the motorcyclist in these three hours.

Please provide additional information or equations to solve the problem accurately.
