Question

Коля живет от миши на растоянии 2,4 км этот путь коля проехал на вилосепеде за 0,4 часа со скоростью 6 кмч а обратный путь по той же дороге он проехал со скоростью 8 кмч на какой путь коля потратил меньше времени и на сколько? нет ли лишних данных в задаче?если есть то какие,имено?

Answer 1

1) 2,4 : 6 = 0,4 (ч) потратил на путь к Мише
2) 2,4 : 8 = 0,3 (ч) потратил на обратный путь
3) 0,4-0,3=0,1 (ч) потратил меньше на обратный путь
Ответ: на 0,1 часа меньше

Answer 2

Problem Analysis

The problem involves determining the time taken by Kolya to travel a certain distance at different speeds and comparing the time taken for the forward and return journeys.

Given Data

- Distance from Mishka to Kolya: 2.4 km - Speed for forward journey: 6 km/h - Speed for return journey: 8 km/h

Time Calculation

To calculate the time taken for each journey, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

For the forward journey: \[ \text{Time}_\text{forward} = \frac{2.4 \, \text{km}}{6 \, \text{km/h}} \]

For the return journey: \[ \text{Time}_\text{return} = \frac{2.4 \, \text{km}}{8 \, \text{km/h}} \]

Let's calculate the time taken for each journey.

Time Calculation

The time taken for the forward journey: \[ \text{Time}_\text{forward} = \frac{2.4 \, \text{km}}{6 \, \text{km/h}} = 0.4 \, \text{hours} \]

The time taken for the return journey: \[ \text{Time}_\text{return} = \frac{2.4 \, \text{km}}{8 \, \text{km/h}} = 0.3 \, \text{hours} \]

Conclusion

- Kolya spent less time on the return journey. - The time difference is 0.1 hours.

Extra Data in the Problem

The extra data in the problem includes irrelevant information such as unrelated search snippets and irrelevant numerical data (e.g., 25, 36, 4, 36, 4, 1.5, 10, 4, 3.2, 5.82, 2.4, 6, 8, 2, 3, 7, 11, 13, 17, 19, 600, 1000). These do not contribute to solving the problem and can be considered as unnecessary data.
