Question

Снега уборочные машины работая одновременно за 1 час могут очистить не более 17 километров дороги шириной 10 метров Сколько потребуется таких же машина для очистки Московской кольцевой автодороги длина которой около 109 км ширина около 38 метров если очистку необходимо произвести не более чем за 3 часа

Answer 1

1: ск.км дороги очистят 3 машины за 3 часа?
2:17*3= 51 (км)Сколько потребуется машин для чистки  дороги шириной 38 м?( округляем до 40м)
40:10*3= 12 (маш), ( если с десятичными дробями то 38 :10 8 3 =  11,4 машины, что теоретически не возможно) 
3; Во сколько раз длина кольцевой автодороги больше, чем могут очистить три машины за 3 часа?
109 : 51 = 2 (раза) приблизительно
4 ;Сколько потребуется машин для очистки кольцевой автодороги?
12*2=24
Ответ, потребуется 24 машины

Answer 2

Calculation of Snow Removal Machines Needed

To calculate the number of snow removal machines needed to clear the Moscow Ring Road (MKAD), we need to consider the following information:

- Each snow removal machine can clear a maximum of 17 kilometers of road with a width of 10 meters in 1 hour. - The Moscow Ring Road has a length of approximately 109 kilometers and a width of about 38 meters. - The snow removal needs to be completed within 3 hours.

To determine the number of machines needed, we can calculate the total area of the road and divide it by the area cleared by each machine in 1 hour.

Calculation Steps:

1. Calculate the total area of the Moscow Ring Road: - Length: 109 kilometers = 109,000 meters - Width: 38 meters - Total area = Length x Width = 109,000 meters x 38 meters = 4,142,000 square meters

2. Calculate the area cleared by each machine in 1 hour: - Width: 10 meters - Area cleared by each machine in 1 hour = Length x Width = 17 kilometers x 10 meters = 170,000 square meters

3. Calculate the number of machines needed: - Total area of the road: 4,142,000 square meters - Area cleared by each machine in 1 hour: 170,000 square meters - Number of machines needed = Total area of the road / Area cleared by each machine in 1 hour = 4,142,000 square meters / 170,000 square meters = 24.36 machines

Since we cannot have a fraction of a machine, we would need to round up to the nearest whole number. Therefore, we would need 25 snow removal machines to clear the Moscow Ring Road within 3 hours.

Please note that this calculation assumes that the snow removal machines can operate continuously without any downtime or delays.
