Question

В первый день снегоуборочная машина очистила 59 км дороги,во второй день- на 8 км меньше,чем в первый, а в третий день-50 км. Всего в эти дни она работала 20 ч. Сколько километров дороги машина очищала за один час,работая с одинаковой производительностью труда?

Answer 1

1) 59-8=51(км)- очистила снегоуборочная машина за 2 день. 2) 59+51+50=160(км)- всего очистила снегоуборочная машина. 3)160:20=8(км\ч)- очищала снегоуборочная машина за 1 час. Ответ: 8 км\ч.

Answer 2

59-8=51км-во 2 день
59+51+50=160км-за 3 дня
160:20=8км-за 1 час

Answer 3

Calculation of Road Clearing Efficiency

To calculate the distance of road cleared per hour by the snowplow, we need to analyze the information provided.

- On the first day, the snowplow cleared 59 km of road. - On the second day, it cleared 8 km less than the first day. - On the third day, it cleared 50 km of road. - The snowplow worked for a total of 20 hours.

To find the distance of road cleared per hour, we need to determine the total distance cleared and divide it by the total number of hours worked.

Let's calculate the total distance cleared by the snowplow:

- First day: 59 km - Second day: 59 km - 8 km = 51 km - Third day: 50 km

Total distance cleared = 59 km + 51 km + 50 km = 160 km

Now, let's calculate the distance of road cleared per hour:

Distance cleared per hour = Total distance cleared / Total hours worked

Distance cleared per hour = 160 km / 20 hours = 8 km/h.

Therefore, the snowplow cleared an average of 8 kilometers of road per hour, working with the same level of productivity.
