Question

Задача. две игрушечные машинка находятся на расстоянии 8568 мм одна от другой. Одновременно они начинают двигаться в противоположных направлениях со скоростями 740мм мин и 688мм мин. Какое расстояние будет между машинками через 5 мин?

Answer 1

740*5=3700

688*5=3440

3440+3700=7140

7140+8568=15708

Answer 2

1) 740+688=1428 (мм/мин) скорость удаления

2) 1428*5+8568=15708 (мм)будет между ними через 5 мин

Ответ: через 5 минут между ними будет 15708 мм.

Answer 3

Problem Analysis

We have two toy cars that are initially 8568 mm apart from each other. They start moving in opposite directions with speeds of 740 mm/min and 688 mm/min. We need to find the distance between the cars after 5 minutes.

Calculation

To find the distance between the cars after 5 minutes, we need to calculate the total distance covered by each car in 5 minutes and then find the difference between their positions.

Let's calculate the distance covered by each car in 5 minutes:

Car 1: Speed of Car 1 = 740 mm/min Time = 5 minutes Distance covered by Car 1 = Speed * Time = 740 mm/min * 5 min = 3700 mm

Car 2: Speed of Car 2 = 688 mm/min Time = 5 minutes Distance covered by Car 2 = Speed * Time = 688 mm/min * 5 min = 3440 mm

Now, let's find the final distance between the cars by subtracting the distance covered by Car 2 from the initial distance between the cars:

Final distance between the cars = Initial distance - Distance covered by Car 2 = 8568 mm - 3440 mm = 5128 mm

Answer

The distance between the two toy cars after 5 minutes will be 5128 mm.
