Question

За три дня теплоход прошёл 800км За два дняпрошёл на 24 км меньше,чем за первый И на 56 км меньше ,чем за третий сколько км прошёл за второй день?

Answer 1

х км - теплоход прошёл за второй день

(х + 24) км - теплоход прошёл за первый день

(х + 56) км - теплоход прошёл за третий день

х + х + 24 + х + 56 = 800

3х + 80 = 800

3х = 800 - 80

3х = 720

х = 720 : 3

х = 240 км - теплоход прошёл за второй день

240 + 24 = 264 км - теплоход прошёл за первый день

240 + 56 = 296 км 

Answer 2

За два дня х км
за 1 день х+24км
за третий х+56км
всего 800км
х+х+24+х+56=800
3х=800-24-56
3х=720 х=240км
за 1 день 240+24=264км
за 3 день 240+56=296км
за 2 день 800-(264+296)=240км
ответ: 240км

Answer 3

Calculation of Distance Traveled on Each Day

To calculate the distance traveled on each day, let's assign variables to the distances traveled on the first, second, and third days.

Let: - Distance traveled on the first day = x km - Distance traveled on the second day = y km - Distance traveled on the third day = z km

According to the given information: - The total distance traveled in three days is 800 km. - The distance traveled on the second day is 24 km less than the distance traveled on the first day. - The distance traveled on the second day is 56 km less than the distance traveled on the third day.

Based on these conditions, we can create the following equations:

1. x + y + z = 800 (equation 1) 2. y = x - 24 (equation 2) 3. y = z - 56 (equation 3)

To find the distance traveled on the second day, we need to solve these equations simultaneously.

Solving the Equations

Let's solve equations 2 and 3 for x and z, respectively, in terms of y:

From equation 2: x = y + 24 From equation 3: z = y + 56

Substituting these values into equation 1, we get:

(y + 24) + y + (y + 56) = 800

Simplifying the equation:

3y + 80 = 800 3y = 800 - 80 3y = 720 y = 720 / 3 y = 240

Calculation of Distance Traveled on the Second Day

Therefore, the distance traveled on the second day is 240 km.

Conclusion

Based on the given information, the distance traveled on the second day is 240 km.
