2 мин 27с = 60с+60с+27с = 147с
9 ч 15 мин = 60*9+15мин=555мин
6 сут 3 ч = 24*6+3ч=147ч
1200с = 1200:60 = 20с

как читать этот текст перевод не нужен
The day of the surfing competition was hot and sunny.
The waves were very big but Nick was a strong swimmer and his new board was good. He sat on it in the water and waited.
A big wave arrived and Nick started to swim strongly. Nick caught the wave well and stood up on his board. The people on the beach watched — it was exciting to watch. Suddenly Nick heard a noise.
A surfboard hit his right arm. He fell from his board. A second big wave hit him and he saw Brian’s board coming at him.
His head went under the water. The water was in his mouth. His arm was hurt. He started to swim but it was not easy.
