The towel on the wall… It’s our ancient custom. There was not a single Ukrainian house , which would not be decorates with towels. A house without a towel was compared with a family without children. A towel symbolized not only aesthetic taste , it was a face of a house and of a hostess. The towels proved that the hostess was tidy and hard-working.
A newly-born child was handed with the towel, guests were met with bread and salt on the towel. A son , a husband, a father were seen off with the towel. While getting married the newly-formed family was standing on a towel too. Bread and salt on an embroidered towel were a symbol of hospitality of the Ukrainian people. To take the towel , to kiss bread symbolized unity, peace, love , understanding among people. This custom has a good tradition in our country.
Towel were used in different ceremonies and in everyday life as well: for wiping a face and hands, for drying dishes, for decorating the houses, for presenting dear people. The ornaments and colours of towels were different in different regions. A lot of songs about the embroidered towel have been created in Ukraine. Объяснение:
t=120:X
Потом он ехал со скоростью 1,2 Х те же 120 км, плюс остановка в пути 15 минут, это 0,25 часа (15:60=0,25).
Можем составить уравнение:
120:Х =120:1,2Х + 0,25
Приводим к общему знаменателю, это 1,2Х , подписываем дополнительные множители, перемножаем и получаем новое уравнение:
144 = 120 + 0,3Х
-0,3Х = 120 - 144
-0,3Х = - 24
0,3Х = 24
Х = 24 : 0,3
Х = 80 (км\час, первоначальная скорость мотоциклиста).
ПРОВЕРКА:
120:80=1,5 (часа)
120:96+0,25=1,5(часа).
