Question

Помогите пожалуйста. лыжники за три дня прошли 87 км. В первый день они прошли 35% всего пути, во второй - 38%, а в третий - остальной путь. 1) какая величина приходится на 1% 2) сколько километров лыжники прошли в 1 день. 3) сколько километров лыжники прошли во 2 день 4) сколько километров лыжники прошли в 3 день.

Answer 1

1) 87:100=0,87 км - приходится на 1%
2) 0,87*35=30,45 км - пройдено в первый день
3) 0,87*38=33,06 км - пройдено во второй день
4) 87-30,45-33,06=20,49 км - пройдено в третий день

Answer 2

Calculation of Distances for Each Day

To answer the questions, let's break down the information provided:

- The skiers covered a total distance of 87 km in three days. - On the first day, they covered 35% of the total distance. - On the second day, they covered 38% of the total distance. - On the third day, they covered the remaining distance.

Let's calculate the distances for each day:

1. Distance covered on the first day: - The skiers covered 35% of the total distance. - To find the distance covered on the first day, we need to calculate 35% of 87 km. - 35% of 87 km = 0.35 * 87 km = 30.45 km.

2. Distance covered on the second day: - The skiers covered 38% of the total distance. - To find the distance covered on the second day, we need to calculate 38% of 87 km. - 38% of 87 km = 0.38 * 87 km = 33.06 km.

3. Distance covered on the third day: - The skiers covered the remaining distance on the third day. - To find the distance covered on the third day, we need to subtract the distances covered on the first and second days from the total distance. - Total distance - Distance covered on the first day - Distance covered on the second day = Distance covered on the third day. - 87 km - 30.45 km - 33.06 km = 23.49 km.

Now, let's answer the specific questions:

1. The value of 1%: - To find the value of 1%, we need to divide the total distance by 100. - Value of 1% = 87 km / 100 = 0.87 km.

2. Distance covered on the first day: - The skiers covered 30.45 km on the first day.

3. Distance covered on the second day: - The skiers covered 33.06 km on the second day.

4. Distance covered on the third day: - The skiers covered 23.49 km on the third day.

To summarize: - The value of 1% is 0.87 km. - The skiers covered 30.45 km on the first day. - The skiers covered 33.06 km on the second day. - The skiers covered 23.49 km on the third day.
