Question

Мастер изготавливает за 1час 28деталей,а его ученик в 2раза меньше.сколько деталей изготовят мастер и ученик за 8часов,если будут работать вместе.

Answer 1

Мастер-28
следовательно ученик 28:2=14
вместе за 8 ч - ( 28+14)*8=336(деталей) изготовят ученик и мастер за 8 часов.
Ответ:336 деталей

Answer 2

1)28:2=14 (дет.)-изготовляет ученик;
2)28+14=42 (дет.)-изготовляют за 1 час вместе;
3)42×8=336 (дет.)-изготовят мастер и ученик за 8 часов.
Ответ:336 деталей.

Answer 3

Calculating the Production of Master and Apprentice

To calculate the total number of parts produced by the master and the apprentice working together for 8 hours, we can follow these steps:

1. Calculate the production rate of the master and the apprentice per hour. 2. Add their individual production rates to find the combined production rate per hour. 3. Multiply the combined production rate by the total number of hours they work together.

Production Rate Calculation

The master produces 28 parts in 1 hour, and the apprentice produces 2 times fewer parts. This means the apprentice produces 28 / 2 = 14 parts in 1 hour.

Combined Production Rate

The combined production rate per hour when the master and the apprentice work together is 28 + 14 = 42 parts per hour.

Total Production in 8 Hours

Now, to find the total production when they work together for 8 hours: Total production = Combined production rate * Total hours Total production = 42 * 8 = 336 parts

Therefore, when the master and the apprentice work together for 8 hours, they will produce a total of 336 parts.
