Question

чтобы узнать расстояние от дома дор реки, Костя выйдя издома начал считать шаги, и у реки он насчитал 1386 шагов, а на обратном пути 1400 шагов.Узнай сколько в среднем шагов сделал Костя? Найди расстояние от дома до реки, если средняя длина шага 3 дм. Вырази ответ в метрах и дециметрах

Answer 1

1)(1386+1400):2=1393(ш)- средних шагов.

2)1393*3=4179(дм)=41790(м)-расстояние от дома до реки.

 

Answer 2

1) 1 386 + 1 400 =2 786 ( шаг) -всего

2) 2 786 : 2 =1 393 (шага) - в среднем сделал Костя

3) 1 393 * 3 =4 179 (дм ) - расстояние. или 417 м 9 дм.

Ответ : расстояние от дома до реки 417 м 9 дм .

Answer 3

Calculation of Average Steps and Distance

To find out how many steps Kostya took on average, we can calculate the mean of the number of steps he took on the way to the river and on the way back.

On the way to the river, Kostya took 1386 steps, and on the way back, he took 1400 steps To find the average, we can add these two numbers together and divide by 2:

(1386 + 1400) / 2 = 2786 / 2 = 1393 steps

Therefore, Kostya took an average of 1393 steps.

To calculate the distance from Kostya's home to the river, we need to know the length of his average step. Given that the average length of Kostya's step is 3 decimeters (dm), we can convert this to meters by dividing by 10:

3 dm / 10 = 0.3 meters

To find the total distance, we can multiply the average number of steps by the length of each step:

1393 steps * 0.3 meters = 417.9 meters

Therefore, the distance from Kostya's home to the river is approximately 417.9 meters. This can also be expressed as 41.79 decimeters.
