Question

Рабочий должен был изготовить за день 63 детали Через 2 часа работы ему осталось делать 45 деталей За сколько часов он изготовит оставшиеся детали если выработка за час не изменится помогите ! быстрее

Answer 1

1 63 минус 45 равно 18 2 18 разделить на 29 и 3 45 разделить на 9

Answer 2

1) 63-45=18(д) за 2 часа
2) 18:2=9(д) за один час
3) 45:9=5(ч)

Answer 3

Calculating the Remaining Work

To calculate the time it will take for the worker to complete the remaining 45 parts, we can use the concept of work done.

Given: - Total parts to be made in a day = 63 - Remaining parts to be made after 2 hours of work = 45

The worker has already worked for 2 hours and made 63 - 45 = 18 parts.

Calculating Work Rate

To find the worker's work rate, we can use the formula: \[ \text{Work Rate} = \frac{\text{Work Done}}{\text{Time Taken}} \]

Using the given information, we can calculate the work rate of the worker.

\[ \text{Work Rate} = \frac{18}{2} = 9 \text{ parts/hour} \]

Calculating Time to Complete Remaining Work

Now, to find the time it will take for the worker to complete the remaining 45 parts, we can use the formula: \[ \text{Time} = \frac{\text{Work}}{\text{Work Rate}} \]

\[ \text{Time} = \frac{45}{9} = 5 \text{ hours} \]

Therefore, if the worker's work rate remains constant, it will take him 5 hours to complete the remaining 45 parts.
