Question

За первый месяц отремонтировали 36% всей дороги, за второй месяц 34%, а за третий месяц отремонтировали 42 км. Сколько всего километров дороги отремонтировали?

Answer 1

Ответ:

Пошаговое объяснение:

100% - 36% - 34% = 30% осталось отремонтировать это

составляет 42 км

Составим пропорцию:

42 км - 30%

х км -  100%

х = 42 * 100% : 30%

х= 140 км всего дороги отремонтировали

Answer 2

Ответ:

140 км

Пошаговое объяснение:

Вся дорога = 100%

1) 36 + 34 = 70 (%) - дороги отремонтировали за два месяца

2) 100 - 70 = 30 (%) - дороги отремонтировали за третий месяц

3) 30% = 42 км; 30% = 30 : 100 = 0,3

42 : 0,3 = 140 (км) - дороги отремонтировали за 3 месяца

Answer 3

Calculation of Total Kilometers of Road Repaired

To calculate the total number of kilometers of road repaired, we need to add up the distances repaired in each month.

According to the information provided: - In the first month, 36% of the entire road was repaired. - In the second month, 34% of the entire road was repaired. - In the third month, 42 kilometers of road were repaired.

To calculate the total kilometers of road repaired, we can use the following steps:

1. Calculate the percentage of the road repaired in the first month: - Multiply the percentage (36%) by the total length of the road. - Let's assume the total length of the road is x kilometers. - The distance repaired in the first month is 0.36x kilometers.

2. Calculate the percentage of the road repaired in the second month: - Multiply the percentage (34%) by the total length of the road. - The distance repaired in the second month is 0.34x kilometers.

3. Add the distance repaired in the third month (42 kilometers).

4. Sum up the distances repaired in each month to find the total kilometers of road repaired.

Let's calculate the total kilometers of road repaired step by step:

1. Distance repaired in the first month: 0.36x kilometers. 2. Distance repaired in the second month: 0.34x kilometers. 3. Distance repaired in the third month: 42 kilometers.

To find the total kilometers of road repaired, we need to add these distances together:

Total kilometers of road repaired = Distance repaired in the first month + Distance repaired in the second month + Distance repaired in the third month.

Let's calculate the total kilometers of road repaired using the given information:

Total kilometers of road repaired = 0.36x + 0.34x + 42.

Unfortunately, we don't have the exact total length of the road (x) to provide an accurate answer. If you have the total length of the road, please provide it so we can calculate the total kilometers of road repaired.
