Question

Какую часть улицы асфальтирует машина за 1 час, если асфальтирование всей улицы требуется 4 ч? 2,5ч? 1,5ч?

Answer 1

1/4 часть улицы за час, если 4 часа на всю улицу
2/5часть улицы за час, если 2,5 часа на всю улицу
2/3 часть улицы за час, если 1,5 часа на всю улицу

Answer 2

Calculating Asphalt Paving Rate

To calculate the rate at which the machine paves the street, we can use the formula:

Rate = Length of Street / Time

Let's calculate the rate for each given time:

1. For 4 hours: - Rate = Length of Street / 4 hours - The snippet from Source mentions that the length of the street is 300 meters.

Using the formula: - Rate = 300 meters / 4 hours - Rate = 75 meters per hour.

2. For 2.5 hours: - Rate = Length of Street / 2.5 hours

Using the previously mentioned rate: - Rate = 75 meters per hour - Rate = 75 meters per hour.

3. For 1.5 hours: - Rate = Length of Street / 1.5 hours

Using the previously mentioned rate: - Rate = 75 meters per hour - Rate = 75 meters per hour.

Conclusion

The rate at which the machine paves the street is 75 meters per hour for all the given time durations.
