Question

охотничья собака бежала за зайцем со скоростью 16 метров в секунду а заяц убегал от нее со скоростью 12 метров в секунду -собака догнала зайца за 13 секунд какое расстояние было между ними первоначально

Answer 1

1) 16-12=4м/с разница
2) 4*13=52м
Ответ:52м

Answer 2

S=Vt
16x13=228 м пробежала собака
12х13=156м пробежал заяц
228-156=72м было между ними расстояние
ответ:72м

Answer 3

Calculation of the Initial Distance

To calculate the initial distance between the hunting dog and the hare, we can use the formula:

Distance = Speed x Time

Given that the hunting dog runs at a speed of 16 meters per second and catches up to the hare in 13 seconds, and the hare runs at a speed of 12 meters per second, we can calculate the initial distance.

Let's denote the initial distance as 'D'.

The time it takes for the hunting dog to catch up to the hare is 13 seconds. During this time, the hunting dog covers a distance of 16 meters per second x 13 seconds = 208 meters.

At the same time, the hare is running away from the hunting dog at a speed of 12 meters per second. Therefore, the hare covers a distance of 12 meters per second x 13 seconds = 156 meters.

To find the initial distance, we subtract the distance covered by the hare from the distance covered by the hunting dog:

D = Distance covered by the hunting dog - Distance covered by the hare

D = 208 meters - 156 meters

D = 52 meters

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