Коля,идущий со скоростью 80м/мин,уронил варежку. Таня,идущая за Колей на расстоянии 240 м,увидела,что он что-то уронил,добежала до варежки,подняла её и бросилась догонять Колю со скоростью 160м/мин. Через сколько минут Таня догнала Колю?

Answer 1

1)160-80=80км/ч-скорость сближения.

2)240:80=через 3 минуты.

Answer 2

240/80=3минуты таня шла до упавшей варежки

240/160=1,5 минуты Таня догоняла Колю

Answer 3

Problem Analysis

In this problem, we are given that Kolya is walking at a speed of 80 m/min and drops a glove. Tanya, who is walking behind Kolya at a distance of 240 m, sees him drop something and runs to pick it up. Tanya then starts running towards Kolya at a speed of 160 m/min. We need to determine how many minutes it takes for Tanya to catch up to Kolya.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between Tanya and Kolya is the difference between their individual speeds. In this case, the relative speed is 160 m/min - 80 m/min = 80 m/min.

Since Tanya starts 240 m behind Kolya and their relative speed is 80 m/min, it will take Tanya (240 m) / (80 m/min) = 3 minutes to catch up to Kolya.

Therefore, Tanya will catch up to Kolya in 3 minutes.

Answer

Tanya will catch up to Kolya in 3 minutes.
