Question

В лесном питомнике Ира и Дима обработали саженцы елей от вредителей. За 10 минут Ира обрабатывает 20 саженцев, а Дима 30. Сколько саженцев они обработают за один час, работая вместе и с той же производительностью? Отмететь голочкой правильное решение задачи. 20х6 + 30х6 (20+30)х10 (20+30)х6 20х10+30х10

Answer 1

20×6+30×6=300
(20+30)×6=300 этот вариант тоже верный

Answer 2

За час
20*6+30*6
Значит решение номер 1 и номер 3 верны

Answer 3

To find out how many seedlings they will process in one hour while working together at the same productivity level, we can use the following steps:

Step 1: Calculate the number of seedlings Ira can process in one hour. Since Ira can process 20 seedlings in 10 minutes (1/6 of an hour), we can multiply this by 6 to find the number of seedlings she can process in one hour: 20 * 6 = 120 seedlings/hour

Step 2: Calculate the number of seedlings Dima can process in one hour. Similarly, since Dima can process 30 seedlings in 10 minutes (1/6 of an hour), we can multiply this by 6 to find the number of seedlings he can process in one hour: 30 * 6 = 180 seedlings/hour

Step 3: Add the number of seedlings processed by Ira and Dima in one hour. To find the total number of seedlings they can process in one hour while working together, we add the number of seedlings processed by Ira and Dima: 120 + 180 = 300 seedlings/hour

Therefore, when working together at the same productivity level, Ira and Dima can process 300 seedlings in one hour.
