8 часов

Пошаговое объяснение:

ЭТА ЗАДАЧА НА ОБРАТНУЮ ПРОПОРЦИЮ. Т.е. чем больше рабочих, тем меньше времени надо для работы

4 раб. - 32 часа

16 раб. = х часов

Отсюда

4/16=х/32

х=4*32/16

х=8

To tell you the truth, it is not so easy for me to speak about myself but I'll try to do my best. First of all let me introduce myself My name is olga, olya for short. So I am eighteen now As for my appearance, you can judge yourself. I think there is nothing special in my appearance to attract attention. I am neither tall nor short. I am of medium height like my parents. My parents believe I am slim, but to my mind I am a bit plump and need to lose weight. My hair is straight and long, I do not like a haircut. I wear my hair either loose or done in a knot which becomes me most. I am like my father about my face. But my blue and close- set eyes resemble my mothers. My fathers eyes are hazel. Unfortunately, I am short-sighted. I wish I did not have to wear glasses. My friends say I am easy to deal with but I am always a little unsure of myself, a little too nervous of what other people might say about me. I wish I were more reserved. I am stubborn and never drop my work halfway, always trying to achieve the goal I set. It is dificult to put me off if I have made up my mind to do something. That is why my interests do not change much with the time. As I am interested in ancient history, I prefer reading historical novels when I have some free time. When I am tired, I listen to music. I am fond of both classical and modern music so my favourite performer is Vanessa Mae. I can play the piano a little but I wish I could play the guitar as well.
