2)175-125= 50 участников показали результат больше часа

======================================= 

Answer 2

Problem Analysis

To solve this problem, we need to find the total number of participants in the competition and then determine how many of them finished in more than one hour.

Total Number of Participants

Given that within the first hour, 125 people finished, which is 5/7 of all participants, we can calculate the total number of participants using this information.

Total number of participants = (125 * 7) / 5

Participants Finishing After the First Hour

The remaining participants finished within the next 15 minutes. We need to calculate how many participants finished after the first hour.

Participants finishing after the first hour = Total number of participants - 125

Solution

Let's calculate the total number of participants and the number of participants finishing after the first hour using the provided information.

Calculation

Total number of participants = (125 * 7) / 5 = 175

Participants finishing after the first hour = 175 - 125 = 50

Therefore, there were 50 participants who finished the competition in more than one hour.
