Question

б) Сашко і Дмитро йдуть по алеї назустріч один одному. Зараз між ними 200 м. Через скільки часу вони зустрінуться, якщо швидкість Сашка 45м/хв, а швидкість Дмитра на 10 м кв більша?​

Answer 1

Ответ:

Пошаговое объяснение:

45+10=55м/хв швидк Дмитра

45+55=100м/хв оба

200÷100=2х

Answer 2

45+10=55м\хв ш. Дмитра
45+55=100м/хв двох
200:100=2 хв

Answer 3

To find out when Sasha and Dmitry will meet, we need to calculate the time it takes for them to cover the distance between them. We are given that the distance between them is 200 meters and that Sasha's speed is 45 m/min.

To determine Dmitry's speed, we are told that it is 10 m/min faster than Sasha's speed. Therefore, Dmitry's speed is 45 m/min + 10 m/min = 55 m/min.

To calculate the time it takes for them to meet, we can use the formula:

Time = Distance / Speed

Substituting the given values, we have:

For Sasha: Distance = 200 meters Speed = 45 m/min

For Dmitry: Distance = 200 meters Speed = 55 m/min

Calculating the time it takes for Sasha to cover the distance: Time = 200 meters / 45 m/min = 4.44 minutes (rounded to two decimal places)

Calculating the time it takes for Dmitry to cover the distance: Time = 200 meters / 55 m/min = 3.64 minutes (rounded to two decimal places)

Since Dmitry takes less time to cover the distance, we can conclude that they will meet after approximately 3.64 minutes.

Please note that the above calculation assumes a constant speed for both Sasha and Dmitry throughout their journey.
