Question

Рабочие за 3 дня построили мост длиной 360 м, шириной 10 м. Сколько метров длины моста шириной 12 м они построят за 8 дней?

Answer 1

1) (360*10):3=1200 (м2) строят
2) 1200*8=9600 (м2) построят
3) 9600:12=800 (м) длина
Ответ: 800 м длина моста

Answer 2

Calculation of the Length of the Bridge

To calculate the length of the bridge that can be built in 8 days with a width of 12 meters, we can use the information provided about the construction of a bridge with a length of 360 meters and a width of 10 meters in 3 days.

Let's assume that the rate of construction remains constant. We can calculate the rate of construction per day by dividing the length of the bridge built in 3 days by 3:

Rate of construction per day = Length of bridge built in 3 days / 3

Using the given information, the rate of construction per day is:

Rate of construction per day = 360 meters / 3 = 120 meters per day.

Now, we can calculate the length of the bridge that can be built in 8 days with a width of 12 meters:

Length of bridge = Rate of construction per day * Number of days

Substituting the values:

Length of bridge = 120 meters per day * 8 days = 960 meters.

Therefore, the workers will be able to build a bridge with a length of 960 meters and a width of 12 meters in 8 days.

Please note that the calculation assumes a constant rate of construction and does not take into account any potential limitations or variations in the construction process.
