Question

Две мвшинки двинулись одновременно в противоположном направлении. Первая шла со скоростью 6 дм/с, вторая 7 дм/с 1) нас колько дециметров машинки удалялись докг от другакаждую секунду? 2) какое расстояние будет между ними через 3 с

Answer 1

6+7=14 дм/с- машинки удалятся друг от друга
14•3=42 дм- такое расстояние будет между ними через 3 секунды

Answer 2

1) 6+7=13(дм/с)-ответ на 1 вопрос.
2)13*3=39(дм)-ответ на 2 вопрос.

Answer 3

Calculation of the Distance between the Cars

To calculate the distance between the two cars, we need to determine how far each car travels in a given time period.

1) The first car is traveling at a speed of 6 dm/s (decimeters per second), and the second car is traveling at a speed of 7 dm/s. We need to find out how many decimeters each car moves in one second.

- The first car moves 6 decimeters per second. - The second car moves 7 decimeters per second.

2) Now, let's calculate how far apart the cars will be after a specific time period of 3 seconds.

- The first car will have traveled 6 decimeters/s * 3 s = 18 decimeters. - The second car will have traveled 7 decimeters/s * 3 s = 21 decimeters.

Therefore, after 3 seconds, the two cars will be 21 decimeters - 18 decimeters = 3 decimeters apart.

So, the answers to the given questions are: 1) The cars will be 18 decimeters apart after each second. 2) After 3 seconds, the distance between the cars will be 3 decimeters.
