Answer 1

Ответ:

а) 1650 слов

б) 3 часа

в) 230 деталей в день

г) 180 страниц

Пошаговое объяснение:

110×15=1650 слов

б) 360:120=3ч

в) 1150:5=230 (д.)/д.

г) 20×2=40 (стр.)-читает сестра за день

(20+40)×3=180 (стр.)-они прочитают вместе за 3 дня.

Answer 2

Task a)

Andrey reads at a speed of 110 words per minute. We need to find out how many words he will read in a quarter of an hour.

To solve this, we can use the formula:

Number of words = Speed * Time

Given that the speed is 110 words per minute and the time is a quarter of an hour (15 minutes), we can substitute these values into the formula:

Number of words = 110 * 15

Calculating this, we find that Andrey will read 1650 words in a quarter of an hour.

Task b)

The mother makes 120 dumplings in one hour. We need to find out how long she worked if she made a total of 360 dumplings.

To solve this, we can use the formula:

Time = Total Dumplings / Dumplings per Hour

Given that the total number of dumplings is 360 and the number of dumplings made per hour is 120, we can substitute these values into the formula:

Time = 360 / 120

Calculating this, we find that the mother worked for 3 hours.

Task c)

The turner produced 1,150 parts in 5 working days. We need to find out the productivity rate at which he worked.

To solve this, we can use the formula:

Productivity Rate = Total Parts / Number of Days

Given that the total number of parts produced is 1,150 and the number of working days is 5, we can substitute these values into the formula:

Productivity Rate = 1,150 / 5

Calculating this, we find that the turner worked at a productivity rate of 230 parts per day.

Task d)

Maria reads 20 pages per day, which is half as much as her older sister. We need to find out how many pages they will read together in 3 days.

To solve this, we need to find out how many pages Maria's older sister reads per day. Since Maria reads half as much as her older sister, her older sister reads 40 pages per day.

To find out how many pages they will read together in 3 days, we can use the formula:

Total Pages = (Maria's Pages + Sister's Pages) * Number of Days

Given that Maria reads 20 pages per day and her older sister reads 40 pages per day, and the number of days is 3, we can substitute these values into the formula:

Total Pages = (20 + 40) * 3

Calculating this, we find that they will read a total of 180 pages together in 3 days.
