Question

Из пунктов А и В одновременно навстречу друг другу вышли два пешехода.Один из них за 1 час проходит 1/6 расстояния АВ, а другой - 1/5 расстояния АВ. На какую часть расстояния АВ они сближаются каждый час??? Помогите пожалуйста, надежда только на вас!!!!

Answer 1

1/6+1/5=5/30+6/30=11/30
ответ: на 11/30АВ

Answer 2

Problem Analysis

We have two pedestrians walking towards each other from points A and B. One of them covers 1/6 of the distance AB in 1 hour, while the other covers 1/5 of the distance AB in 1 hour. We need to determine the fraction of the distance AB that they approach each other every hour.

Solution

To find the fraction of the distance AB that they approach each other every hour, we need to calculate the sum of the fractions covered by each pedestrian in 1 hour.

Let's denote the distance AB as x.

According to the problem, one pedestrian covers 1/6 of the distance AB in 1 hour, which can be represented as (1/6)x.

Similarly, the other pedestrian covers 1/5 of the distance AB in 1 hour, which can be represented as (1/5)x.

To find the fraction of the distance AB that they approach each other every hour, we need to calculate (1/6)x + (1/5)x.

Simplifying the expression, we have:

(1/6)x + (1/5)x = (5/30)x + (6/30)x = (11/30)x

Therefore, they approach each other by 11/30 of the distance AB every hour.

Answer

The pedestrians approach each other by 11/30 of the distance AB every hour.
