Question

Казак три дня ехал верхом. В первый день он проехал 7/19 всего пути, во второй 55% пути, который остался, а в третий остаток 108км. Какое расстояние он преодолел за три дня. .

Answer 1

1 день - 7/19 всего пути

осталось 12/19

2 день 55%(11/20) от того,что осталось(12/19)

(11/20)*(12/19)=33/95 от всего пути

1 день + 2 день=7/19+33/95=35/95+33/95=68/95

значит на 3 день остается 95/95-68/95=27/95 всего пути

27/95 всего пути равно 108км, значит, чтобы найти весь путь, надо 108 разделить на 27 и умножить на 95

108/27*95=380км

Ответ: весь путь составляет 380км

Всё чётко! ;)

Answer 2

Calculation of the Distance Traveled

To calculate the distance traveled by the Kazakh rider over three days, we need to determine the distances covered on each day based on the given information.

According to the information provided: - On the first day, the rider traveled 7/19 of the total distance. - On the second day, the rider traveled 55% of the remaining distance. - On the third day, the rider covered the remaining distance, which is 108 km.

Let's calculate the distance traveled on each day:

1. First Day: The rider traveled 7/19 of the total distance. - Let's assume the total distance is represented by x. - Therefore, the distance covered on the first day is (7/19) * x.

2. Second Day: The rider traveled 55% of the remaining distance. - The remaining distance after the first day is (1 - 7/19) * x. - Therefore, the distance covered on the second day is (55/100) * (1 - 7/19) * x.

3. Third Day: The rider covered the remaining distance, which is 108 km.

To find the total distance traveled over three days, we add up the distances covered on each day.

Let's calculate the total distance traveled:

Total Distance = Distance on First Day + Distance on Second Day + Distance on Third Day

Total Distance = (7/19) * x + (55/100) * (1 - 7/19) * x + 108

Now, let's solve this equation to find the value of x and calculate the total distance traveled.
