2 Реши задачу. Двое косарей вместе скосили траву с 360 м2. Один из них ра-ботал 1 час, другой – 2 часа. С какой площади скосил каждый,если скорость работы (производительность) у них одина-ковая? условие решение ответ ​

Answer 1

Пошаговое объяснение:

Там где уголок там 360 и на верху 2. 4 действие 120*2=240(м и на меру 2). Ответ :1 косарь 120 метров и на верху 2, 2 касорь 240 м и на верху 2. Это точно правильно в классе делали

Answer 2

Problem Statement:

Двое косарей вместе скосили траву с 360 м2. Один из них работал 1 час, другой – 2 часа. С какой площади скосил каждый, если скорость работы (производительность) у них одинаковая?

Solution:

To solve this problem, we can use the concept of work rate. The work rate is the amount of work done per unit of time. Since the work rate is the same for both workers, we can set up the following equation:

Work rate of the first worker * Time taken by the first worker = Work rate of the second worker * Time taken by the second worker

Let's assume that the area of grass mowed by the first worker is x square meters and the area of grass mowed by the second worker is y square meters.

According to the problem, the total area of grass mowed is 360 square meters. So we have the equation:

x + y = 360 (Equation 1)

The work rate of each worker is equal to the area of grass mowed divided by the time taken. Since the work rate is the same for both workers, we have:

x / 1 = y / 2 (Equation 2)

To solve this system of equations, we can rearrange Equation 2 to express x in terms of y:

x = (y / 2) * 1 (Equation 3)

Substituting Equation 3 into Equation 1, we get:

(y / 2) * 1 + y = 360

Simplifying the equation, we have:

y / 2 + y = 360

Combining like terms, we get:

3y / 2 = 360

To solve for y, we can multiply both sides of the equation by 2/3:

y = (2/3) * 360

Evaluating the expression, we find:

y = 240

Substituting the value of y back into Equation 3, we can find the value of x:

x = (240 / 2) * 1

Simplifying the expression, we get:

x = 120

Therefore, the first worker mowed an area of 120 square meters, and the second worker mowed an area of 240 square meters.

Answer:

Each worker mowed the following areas: - The first worker mowed 120 square meters. - The second worker mowed 240 square meters.
