Ответ: за 56 1/4 хв .

Пошаговое объяснение:

45 хв = 45/60 год = 3/4 год .

1) 35 * 3/4 = 105/4 = 26 1/4 ( км ) - відстань між замками

2) 26 1/4 : 28 = 105 * 1/28 = 15/16 ( год ) = 15/16 * 60 хв = 56 1/4 ( хв ) - час

пролітання відстані з меншою швидкістю .

Краткий пересказ на русском, или на английском.
George doesn't like staying at home when he is on holiday. He prefers going somewhere at the seaside. He enjoys
swimming, windsurfing, and diving. Three months ago he was at the Red Sea and when he came back, tanned and happy, he said that he had never have such a terrific holiday before. As he was very good at swimming and diving and was interested in biology, he managed to join a scientific expedition that studied the sea life of the Red Sea coast at that time. The researchers allowed him to help them in their work and gave him a special suit for diving, so he was able to stay deep in the sea for quite a long time. George was amazed how beautiful the underwater world was. Millions of brightly coloured fish moving busily around him. Crabs, turtles, and sea snakes looked at him curiously and then hurried about their underwater business. Once when George followed a little crab, a huge fish appeared from behind a coral rock. Though he had never seen sharks alive,he recognised it at once. Fortunately, the shark took no interest in him and disappeared into the depth as if it had much more important things to do. While George was working for the expedition, exploring the sea plants and animals in their natural conditions, he made a firm decision to go on studying biology and natural sciences as the research work became very attractive to him
