Question

Спортсмен во время тренировки сделал три забега.Второй забег был на 50 м длиннее первого,а третий на 60 м короче второго.Сколько метров составил третий забег,если спортсмен во время тренировки пробежал 610 м?

Answer 1

Пусть х - первый забег, тогда
х+50 - второй забег,
(х+50)-60 - третий забег.
Всего - 610 м.
Уравнение:
х+(х+50)+(х+50)-60=610
х+х+50+х+50-60=610
3х+40=610
3х=610-40
3х=570
х=570:3
х= 190 (м) - первый забег,
190+50=240 (м)- второй забег,
240-60=180(м) - третий забег.

Answer 2

X+(x+50)+(x-60)=610;
x+x+50+x-60=610;
3x-10=610;
3x=620;
x=620:3;

Calculating the Length of the Third Run

To calculate the length of the third run, we can use the information provided about the lengths of the three runs and the total distance covered during the training session.

Given: - The second run was 50 meters longer than the first run. - The third run was 60 meters shorter than the second run. - The total distance covered during the training session was 610 meters.

Let's denote: - Length of the first run as x meters. - Length of the second run as (x + 50) meters. - Length of the third run as (x + 50 - 60) meters.

We know that the total distance covered during the training session was 610 meters, so we can form the equation: x + (x + 50) + (x + 50 - 60) = 610

Solving for x: 3x + 40 = 610 3x = 570 x = 190

Therefore, the length of the third run was (190 + 50 - 60) = 180 meters.

Answer

The length of the third run was 180 meters.
