Пошаговое объяснение:

1) 23,2 + 3,1 = 26,3 (км/ч) - скорость катера по течению

2) 23,2 - 3,1 = 20,1 (км/ч) - скорость катера против течения

3) 2,3 * 20,1 = 46,23 (км) - проплыл катер против течения

4) 1,2 * 26,3 = 31,56 (км) - проплыл катер по течению

5) 46,23 - 31,56 = 14,67 (км) - проплыл катер больше против течения

Ответ: на 14,67 км больше

Harvard University.
Harvard University is a private coeducational institution of higher education, the oldest in the USA. A college was founded by the Great and General Court of the Massachusetts Bay Colony in 1636. It was opened for instruction two years later and was named in 1639 for English clergyman John Harvard, its first sponsor. The main university campus lies along the Charles River in Cambridge, Massachusetts, a few miles west of downtown Boston. The University has grown from nine students with a single master to an enrollment of more than 18 000 degree candidates, including undergraduates and students in 10 principal academic units. An additional 13,000 students are enrolled in one or more courses in the Harvard Extension School. Harvard’s total enrollment is about 20,000. Over 14,000 people work at Harvard, including more than 2,000 faculties. Harvard gradually acquired considerable autonomy and private financial support, becoming a charted university in 1780. From its earliest days, Harvard established and maintained a tradition of academic excellence and the training of citizens for national public service. Harvard’s undergraduate school, Harvard College, contains about one-third of the total student body. The core of the university’s teaching staff consists of the faculty of arts and sciences, which includes the graduate faculty of arts and sciences. The university has graduate or professional schools of medicine, law, business, divinity, education, government, dental medicine, design, and public health. The schools of law, medicine, and business are particularly prestigious. The average college course of study is 4 years. The academic year is usually 9 months or 2 terms (semesters) of four and a half months each. The first-year students are called freshmen. Students choose a major subject (профилирующая дисциплина) and take many courses in this subject. After four years they get a traditional Bachelor’s degree. Then the students may go on to graduate school (старшие курсы) and with a year or two of further study get a Master’s degree and then after another year or two of study and research they may get a still higher degree as Doctor of Philosophy (Ph. D.). The student’s progress is evaluated by means of tests, term works and final examinations in each course. The student’s work is given a mark, usually on a five-point scale (5-балльная система). Letters indicate the level of achievement. “A” is the highest mark, “F” denotes a failure. The methods of instruction in the university are lectures, discussions, laboratory and course works or seminars. By the end of the 20th century Harvard had educated six US presidents – John Adams, John Quincy Adams, Rutherford B. Hayes, Theodore Roosevelt, Franklin D. Roosevelt and John F. Kennedy – and a number of justices, cabinet officers and congressional leaders, literary figures, historians, chemists and naturalists. Задание 6.
