Question

Помогите с задачей пж! Где написано [ ] надо вставить любое число! С двух концов беговой дорожки, длина которой [ ] м, одновременно с одинаковой скоростью, равной [ ] м/с, на встручу друг другу побежали два мальчика. Что можно сказать о времени, за которое бежал каждый из них до встречи? Что можно сказать о расстоянии, которое пробежал каждый из них до встречи?

Answer 1

Можно сказать что они пробежали одинаковое расстояние равное половине дорожки за одинаковое время

Answer 2

Problem Analysis

We have a situation where two boys are running towards each other on a treadmill. The length of the treadmill is given as "m" and the speed of both boys is given as "m/s". We need to determine the time it takes for each boy to reach the meeting point and the distance each boy covers before the meeting.

Solution

Since both boys are running towards each other with the same speed, we can consider their combined speed as the sum of their individual speeds. Therefore, the combined speed of the boys is "2m/s" (m/s + m/s).

To find the time it takes for each boy to reach the meeting point, we can use the formula: time = distance / speed.

Let's assume that the time taken by each boy to reach the meeting point is "t" seconds. Since the distance covered by each boy is the same, we can calculate the distance using the formula: distance = speed * time.

Calculation

Let's substitute the values into the formulas:

- Combined speed of the boys = 2m/s - Time taken by each boy to reach the meeting point = t seconds - Distance covered by each boy = speed * time = (m/s) * t

Answer

Based on the given information, we can say the following:

1. The time taken by each boy to reach the meeting point is "t" seconds. 2. The distance covered by each boy before the meeting is (m/s) * t.

Please note that the specific value of "m" and "t" is not provided in the question, so we cannot determine the exact time and distance without those values.
