Question

Саша и дима идут по аллее навстречу друг к другу. Сейчас между ними 200м. Через сколько времени они встретятся, если скорость саши 45м\мин, а скорость димы на 10м\мин больше?

Answer 1

45+10=55м/мин      45+55=100м/мин     200:100=2мин   ответ 2 минуты

Answer 2

Problem Analysis

We are given that Sasha and Dima are walking towards each other along an alley. The distance between them is currently 200 meters. We are also given that Sasha's speed is 45 m/min and Dima's speed is 10 m/min faster than Sasha's speed.

We need to determine how much time it will take for them to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for Sasha and Dima to meet.

The distance between them is 200 meters.

Sasha's speed is 45 m/min, so the time it will take for Sasha to cover the distance is: time_sasha = distance / speed_sasha = 200 / 45 = 4.44 minutes.

Dima's speed is 10 m/min faster than Sasha's speed, so Dima's speed is 45 + 10 = 55 m/min.

The time it will take for Dima to cover the distance is: time_dima = distance / speed_dima = 200 / 55 = 3.64 minutes.

Since they are walking towards each other, the total time it will take for them to meet is the sum of their individual times: total_time = time_sasha + time_dima = 4.44 + 3.64 = 8.08 minutes.

Therefore, Sasha and Dima will meet in approximately 8.08 minutes.

Answer

Sasha and Dima will meet in approximately 8.08 minutes.

Note: The above calculations are based on the given information and assumptions.
