Answer 1

В первый:
87÷100×35=30.45
Во второй:
87÷100×38=33.06
В третий:
87÷100×(100-(35+38))=23.49

Answer 2

Calculation of Distance Covered Each Day by Skiers

To calculate the distance covered by the skiers each day, we need to follow the given information. Let's break it down step by step:

1. The skiers covered a total distance of 87 km in 3 days. 2. On the first day, they covered 35% of the total distance. 3. On the second day, they covered 38% of the total distance. 4. On the third day, they covered the remaining distance.

Let's calculate the distance covered each day:

1. First Day: - Distance covered on the first day = 35% of the total distance - Distance covered on the first day = 0.35 * 87 km

2. Second Day: - Distance covered on the second day = 38% of the total distance - Distance covered on the second day = 0.38 * 87 km

3. Third Day: - Distance covered on the third day = Remaining distance - Distance covered on the third day = Total distance - Distance covered on the first day - Distance covered on the second day

Let's calculate the distances:

1. First Day: - Distance covered on the first day = 0.35 * 87 km = 30.45 km

2. Second Day: - Distance covered on the second day = 0.38 * 87 km = 33.06 km

3. Third Day: - Distance covered on the third day = 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

Therefore, the skiers covered the following distances each day: - First day: 30.45 km - Second day: 33.06 km - Third day: 23.49 km

Please note that the distances are rounded to two decimal places for simplicity.
