Question

Два токаря должны обработать 240 деталей Первый токарь э Это задание выполняется 5 часов 2 токарь за час обрабатывает на 16 деталей меньше чем 1 Если два токаря будут работать совместно За сколько часов выполнит Это задание

Answer 1

240:5=48 - первый токарь, за час.
48-16=32 - второй токарь, за час.
48+32=80.
240:80=3.
Ответ: Если два токаря будут работать вместе, они закончат задание за три часа

Answer 2

Problem Analysis

To solve this problem, we need to calculate how long it will take two lathe operators to complete the task of processing 240 parts when working together. The first operator takes 5 hours to complete the task alone, while the second operator processes 16 parts less per hour than the first.

Calculating the Combined Work Rate

Let's calculate the combined work rate of the two lathe operators.

The first operator processes 240 parts in 5 hours, so their work rate is: Work rate of first operator = 240 parts / 5 hours = 48 parts per hour

The second operator processes 16 parts less per hour than the first, so their work rate is: Work rate of second operator = 48 parts per hour - 16 parts per hour = 32 parts per hour

The combined work rate of the two operators working together is: Combined work rate = Work rate of first operator + Work rate of second operator

Calculating the Time to Complete the Task

Now, let's use the combined work rate to calculate the time it will take for the two operators to complete the task of processing 240 parts when working together.

Time to complete the task = Total parts / Combined work rate

Substitute the values: Time to complete the task = 240 parts / (48 parts per hour + 32 parts per hour)

Calculation

Let's calculate the time it will take for the two operators to complete the task.
