Question

ПО ПЛАНУ ЗА НЕДЕЛЮ НУЖНО БЫЛО ОТРЕМОНТИРОВАТЬ 850МЕТРОВ ДОРОГИ ЗА 3 ДНЯ БРИГАДА ВЫПОЛНИЛА 40% ЗА 6 ДНЕЙ 85% ЗА 7 ДНЕЙ 100% ЗА 9 ДНЕЙ 130 % ЗАПЛАНИРОВАННОЙ РАБОТЫ СКОЛЬКО МЕТРОВ ДОРОГИ БЫЛО ОТРЕМОНТИРОВАНО В КАЖДОМ СЛУЧАЕ ?

Answer 1

Calculation of Road Repair Progress

To calculate the amount of road that was repaired in each case, we can use the information provided:

- The planned length of road to be repaired was 850 meters. - The brigade completed 40% of the planned work in 6 days. - The brigade completed 85% of the planned work in 7 days. - The brigade completed 100% of the planned work in 9 days. - The brigade completed 130% of the planned work.

Let's calculate the amount of road that was repaired in each case:

1. 40% completion in 6 days: - Percentage of work completed: 40% - Number of days taken: 6 days - Length of road repaired: 40% of 850 meters = 340 meters - Time taken to repair 1 meter of road: 6 days / 340 meters = 0.0176 days/meter

2. 85% completion in 7 days: - Percentage of work completed: 85% - Number of days taken: 7 days - Length of road repaired: 85% of 850 meters = 722.5 meters - Time taken to repair 1 meter of road: 7 days / 722.5 meters = 0.0097 days/meter

3. 100% completion in 9 days: - Percentage of work completed: 100% - Number of days taken: 9 days - Length of road repaired: 100% of 850 meters = 850 meters - Time taken to repair 1 meter of road: 9 days / 850 meters = 0.0106 days/meter

4. 130% completion: - Percentage of work completed: 130% - Length of road repaired: 130% of 850 meters = 1105 meters

Summary of Road Repair Progress

Based on the given information, the length of road that was repaired in each case is as follows:

1. 40% completion in 6 days: 340 meters 2. 85% completion in 7 days: 722.5 meters 3. 100% completion in 9 days: 850 meters 4. 130% completion: 1105 meters

Please note that the calculations assume a linear rate of progress, which may not always be accurate in real-world scenarios.
