Question

Решитп задачу Собака бежала за зайцем со скоростью 16 м с а заяц убегал от нее со скоростью 12 м с собака догнала зайца за 13 с какое расстаяние было между ними первоначально?

Answer 1

16-12=4м/сек скорость сближения (с ней собака догоняет зайца)
4*13=52м было расстояние

Answer 2

Task Solution

To solve the problem, we can use the formula: distance = speed * time. We know the speed of the dog and the hare, as well as the time it took for the dog to catch the hare. Using this information, we can calculate the initial distance between them.

Given: - Speed of the dog (s_dog) = 16 m/s - Speed of the hare (s_hare) = 12 m/s - Time taken for the dog to catch the hare (t) = 13 s

Formula: - Distance = Speed * Time

Calculation

Using the given values, we can calculate the initial distance between the dog and the hare.

1. Distance covered by the dog in 13 seconds: - Distance_dog = s_dog * t - Distance_dog = 16 m/s * 13 s - Distance_dog = 208 m

2. Distance covered by the hare in 13 seconds: - Distance_hare = s_hare * t - Distance_hare = 12 m/s * 13 s - Distance_hare = 156 m

3. Initial distance between the dog and the hare: - Initial_distance = Distance_dog - Distance_hare - Initial_distance = 208 m - 156 m - Initial_distance = 52 m

So, the initial distance between the dog and the hare was 52 meters.
