Answer 1

Ответ:

6 км/ч скорость работы второй бригады

Пошаговое объяснение:

1. 800 : 10 = 80 (км) шоссе две бригады ремонтируют за 1 день = 8 часам

2. 80 : 8 = 10 (км/ч) скорость работы двух бригад

3. 10 - 4 = 6 (км/ч) скорость работы второй бригады

Answer 2

Problem Analysis

We have two brigades working together to repair a 800 km long highway. They plan to complete the work in 10 days, with each day consisting of 8 hours of work. One brigade repairs at a rate of 4 km/h. We need to determine the work rate of the second brigade.

Solution

To find the work rate of the second brigade, we can use the formula:

Work Rate = Total Work / Total Time

The total work is the length of the highway, which is 800 km. The total time is the number of workdays multiplied by the number of work hours per day. In this case, it is 10 days * 8 hours/day = 80 hours.

Let's calculate the work rate of the second brigade.

Calculation

Total work = 800 km Total time = 10 days * 8 hours/day = 80 hours

Work Rate of the second brigade = Total work / Total time

Work Rate of the second brigade = 800 km / 80 hours

Work Rate of the second brigade = 10 km/h

Answer

The work rate of the second brigade is 10 km/h.
