Пошаговое объяснение

1) 1800/2= 900 км прошли путешественники в 1 день

2) 900/2= 450 км прошли путешественники вво 2 день

3) 900+450= 1350км прошли путешественники за 1 и 2 дни

4) 1800-1350= 450 осталось пройти путешестпутешествиннекам

Ответ: 450км

Answer 3

1. To solve the first problem, let's break it down step by step. The travelers have to cover a total distance of 1800 km. On the first day, they covered half of the distance, which is 900 km. On the second day, they covered half of the remaining distance, which is half of 900 km, or 450 km. Therefore, the total distance left to cover is the remaining half of the distance, which is also 450 km. So, there are 450 km left to travel.[[1]]

2. The second problem seems to involve different units of measurement. Let's break it down:

- 18 hours and 45 minutes can be converted to minutes by multiplying 18 by 60 and adding 45, which gives us 1125 minutes. - 10 hours and 54 minutes can be converted to minutes by multiplying 10 by 60 and adding 54, which gives us 654 minutes. - 9 tons and 3 kilograms can be converted to kilograms by multiplying 9 by 1000 and adding 3, which gives us 9003 kilograms. - 7 tons and 4 centners can be converted to kilograms by multiplying 7 by 1000 and adding 4 multiplied by 100, which gives us 7004 kilograms. - 9 kilometers can be converted to meters by multiplying 9 by 1000, which gives us 9000 meters. - 5036 meters can be converted to kilometers by dividing 5036 by 1000, which gives us 5.036 kilometers. - 4 hectares can be converted to acres by multiplying 4 by 2.471, which gives us 9.884 acres. - 300 ares can be converted to hectares by dividing 300 by 100, which gives us 3 hectares. - 10 tons can be converted to kilograms by multiplying 10 by 1000, which gives us 10,000 kilograms. - 8 centners can be converted to kilograms by multiplying 8 by 100, which gives us 800 kilograms. - 34 kilograms can be converted to grams by multiplying 34 by 1000, which gives us 34,000 grams. - 9 centners and 9 kilograms can be converted to kilograms by multiplying 9 by 100 and adding 9, which gives us 909 kilograms.

Therefore, the converted values are: - 18 hours and 45 minutes = 1125 minutes - 10 hours and 54 minutes = 654 minutes - 9 tons and 3 kilograms = 9003 kilograms - 7 tons and 4 centners = 7004 kilograms - 9 kilometers = 9000 meters - 5036 meters = 5.036 kilometers - 4 hectares = 9.884 acres - 300 ares = 3 hectares - 10 tons = 10,000 kilograms - 8 centners = 800 kilograms - 34 kilograms = 34,000 grams - 9 centners and 9 kilograms = 909 kilograms
