Водій 99 км їде з однією швидкістю, 198 км з іншою швидкістю і витрачає весь шлях 3,1 години. Якби він перші 99 км їхав зі швидкістю на 10% менше, а решта 198 км зі швидкістю на 10 % більше, то весь шлях пішло б 3 години. За який час проїде водій весь шлях, якщо перші 99 км їхати зі швидкістю на 10 % більше, а решта 198 км зі швидкістю на 10% менше, ніж він їхав насправді?

A) The public was informed of the Titanic tragedy on the radio. B) The new technology saved a lot of lives. C) Wireless communication affects our lives. D) John Baird got a profound education. E) John Baird and Marconi were rivals Much of the public first learned about radio because of a tragedy. When the luxury liner Titanic struck an iceberg in April 1912, the doomed ship used the new technology to desperately call for help. Only about 700 of the 2,220 passengers were rescued, but the number of survivors might have been much lower if other ships who received the transmission had not arrived. At first, radio functioned as a wireless telegraph, sending pulses of Morse code. American physicist Reginald Fessenden came up with a scheme for modulating radio waves, a technique that made it possible to sound. In 1906 he conducted the first radio broadcast. The first home television receiver was demonstrated in 1928. Wireless communication technologies have transferred the world, bringing news and ideas to far-flung corners of the globe and influencing everything from fashion and language to thе rise and fall of political systems. John Baird, a Scottish engineer, is the first man to televise pictures of objects in motion. Educated at Larchfield Academy, the Royal Technical College, and the University of Glasgow, he produced televised objects in outline in 1924, transmitted recognizable human faces in 1925, and demonstrated the televising of moving objects in 1926 at the Royal Institution, London. The German post office gave him facilities to develop a television service in 1929. When the British Broadcasting Corporation (BBC) television service began in 1936, his system was in competition with one promoted by Marconi Electric and Musical Industries, and in February 1937 the BBC adopted the Marconi EMI system exclusively. Baird demonstrated colour television in 1928 and was report
