Question

Начертил координатный луч и отметь на нём точки: а) A(0), B(1), C(3), D(6), если единичный отрезок равен 1 см б) K(0), E(1), M(2), P(2), если еденичный отрезок равен длине трёх клеток в тетради Сл. Номер От деревни Ивантеево до села Вороново 20 км. Миша шёл из Ивантеево до Воронова со скоростью 5 км/ч, а Витя со скоростью 4км/ч на сколько больше времени потратил Витя, чем Миша?

Answer 1

Вторая задача
от деревни до села 20км
миша 5км/ч витя 4км/ч
20/5 = 4ч - шел миша
20/4 = 5ч - шел витя
Ответ: на 1 час

Answer 2

Drawing a Coordinate Ray and Marking Points

To draw a coordinate ray and mark points on it, we need to understand the given information. Let's break it down:

a) Points A, B, C, and D are given with their respective coordinates: - A(0) - B(1) - C(3) - D(6)

b) Points K, E, M, and P are given with their respective coordinates: - K(0) - E(1) - M(2) - P(2)

We are also given that the length of the unit segment is 1 cm for part a) and the length of the unit segment is equal to the length of three cells in a notebook for part b).

Let's draw the coordinate ray and mark the points:

a) Coordinate Ray with Points A, B, C, and D: - Starting from the origin (0), we can mark the points on the ray: - A(0) - B(1 cm) - C(3 cm) - D(6 cm)

b) Coordinate Ray with Points K, E, M, and P: - Starting from the origin (0), we can mark the points on the ray: - K(0) - E(3 cells) - M(6 cells) - P(6 cells)

Please note that the length of the unit segment is different for parts a) and b), as mentioned in the question.

Calculating the Time Difference between Misha and Vitya

According to the given information: - The distance from the village of Ivanteyevo to the village of Voronovo is 20 km. - Misha walks from Ivanteyevo to Voronovo at a speed of 5 km/h. - Vitya walks from Ivanteyevo to Voronovo at a speed of 4 km/h.

To calculate the time difference between Misha and Vitya, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken by Misha and Vitya separately:

- Misha's time: Time taken by Misha = Distance / Misha's speed = 20 km / 5 km/h = 4 hours - Vitya's time: Time taken by Vitya = Distance / Vitya's speed = 20 km / 4 km/h = 5 hours

Therefore, Vitya took 1 hour more than Misha to travel from the village of Ivanteyevo to the village of Voronovo.
