Question

На лодочной станции надо отремонтировать 192 лодки . В первый день мастер отремонтировал 4 лодки, во второй -5 лодок ,в третий -7,в четвёртый - 8. За какое время он отремонтирует оставшися лодки, если будет работать с такой же средней производителиностью ,что и в первый четыре дня?

Answer 1

1) 4 +5+7+8=24 (л) - отремонтировали за 4 дня
2) 24 : 4= 6 (л) - ремонтировали за один день
3) 192 - 24=168 (л) - осталось отремонтировать
4) 168 : 6=28 (дн) - оставшееся время работы
Ответ. Оставшиеся лодки отремонтируют за 28 дней

Answer 2

Calculation of Average Daily Repair Rate

To determine the time it will take to repair the remaining boats, we need to calculate the average daily repair rate based on the repairs completed in the first four days.

According to the information provided, the repairs completed in the first four days are as follows: - Day 1: 4 boats repaired - Day 2: 5 boats repaired - Day 3: 7 boats repaired - Day 4: 8 boats repaired

To calculate the average daily repair rate, we sum up the number of boats repaired in the first four days and divide it by the number of days: (4 + 5 + 7 + 8) / 4 = 24 / 4 = 6

Therefore, the average daily repair rate is 6 boats per day.

Calculation of Remaining Time

To calculate the time it will take to repair the remaining boats, we divide the number of boats that need to be repaired (192) by the average daily repair rate (6): 192 / 6 = 32

Therefore, it will take 32 days to repair the remaining boats if the master continues to work at the same average daily repair rate as in the first four days.

Please note that this calculation assumes a consistent repair rate and does not account for any potential changes in productivity or external factors that may affect the repair process.
