Question

3км 5м= м 3км 5м= дм 3т 5ц= ц 3ч5мин= мин 3 сут 5ч= ч в лыжной секции занимаются 12 человек нашего класса а в волелольной 8 причем трое из нашего класса сразу в двух секциях сколько всего учеников нашего класса занимаются в этих секциях

Answer 1

3км 5м= 3500м
3км 5м= 30050дм
3т 5ц= 300,5ц
3ч5мин= 185мин
3 сут 5ч= 77 ч

Всего  в классе 12+8-3=17 человек.

Answer 2

Calculation of Distances:

To calculate the sum of distances, we need to convert all the distances to the same unit. Let's convert all the distances to meters (m) first:

- 3 km + 5 m = 3,005 m - 3 km + 5 m = 3,005 m - 3 km + 5 m = 3,005 m - 3 t + 5 c = 3,005 c - 3 h 5 min = 11,100 s - 3 suts + 5 h = 77 h

Therefore, the sum of the distances is 3,005 meters (m).

Number of Students in Sports Sections:

According to the information provided, 12 students from our class are involved in the skiing section, and 8 students are involved in the volleyball section. Additionally, three students from our class are involved in both sections.

To calculate the total number of students from our class involved in these sections, we can add the number of students in each section and then subtract the number of students involved in both sections.

- Number of students in the skiing section: 12 - Number of students in the volleyball section: 8 - Number of students involved in both sections: 3

To calculate the total number of students involved in these sections, we can use the formula:

Total = Number of students in skiing section + Number of students in volleyball section - Number of students involved in both sections

Total = 12 + 8 - 3 = 17

Therefore, a total of 17 students from our class are involved in the skiing and volleyball sections.
