Question

Еж бежит в секунду 2 м это в 2 раза меньше чем бежит заяц за секунду...кто быстрее пробежит расстояние в 20 м? на сколько секунд быстрее?

Answer 1

1)2*2=4 (м/с ) скорость зайца
2) 20:2=10 (сек) за столько пройдёт заяц
3) 20:4=5(сек ) за столько пройдёт заяц
4)10-5=5 (сек) на столько секунд заяц быстрее
Ответ: заяц пробежит быстрее ёжика на 5 секунд .

Answer 2

Who will run faster over a distance of 20 meters, a hedgehog running at a speed of 2 m/s or a hare running at a speed of 5 m/s? By how many seconds will one be faster?

To determine who will run faster over a distance of 20 meters, we need to compare the time it takes for each animal to cover that distance.

Let's calculate the time it takes for the hedgehog to cover 20 meters at a speed of 2 m/s:

Time taken by the hedgehog = Distance / Speed = 20 meters / 2 m/s = 10 seconds

Now, let's calculate the time it takes for the hare to cover 20 meters at a speed of 5 m/s:

Time taken by the hare = Distance / Speed = 20 meters / 5 m/s = 4 seconds

Therefore, the hare will run faster over a distance of 20 meters. The hare will take 4 seconds to cover the distance, while the hedgehog will take 10 seconds. The hare will be 6 seconds faster than the hedgehog.

Please note that the calculations are based on the given speeds and distances and assume constant speed throughout the run.
