Question

От двух противоположных берегов пруда навстречу друг другу поплыли одновременно два пловца и встретились через 10 мин. первый плыл до встречи со скоростью 8м/мин второй со скоростью 12 м мин .найди ширину пруда

Answer 1

1). 8+12=20 (м/мин) скорость сближения; 2). 20*10=200 (м) ширина пруда

Answer 2

Problem Analysis

We have two swimmers who start swimming towards each other from opposite sides of a pond. The first swimmer swims at a speed of 8 m/min, and the second swimmer swims at a speed of 12 m/min. They meet after 10 minutes. We need to find the width of the pond.

Solution

To find the width of the pond, we can use the formula:

Width = (Speed of Swimmer 1 + Speed of Swimmer 2) × Time

Substituting the given values:

Width = (8 m/min + 12 m/min) × 10 min

Simplifying the equation:

Width = 20 m/min × 10 min

Width = 200 meters

Therefore, the width of the pond is 200 meters.
