Question

Ваня бегает со скоростью 7 метров в секунду а коля пробегает 10 метров за полторы секунды. Кто быстрее и на сколько секунд пробежит дестанцию?

Answer 1

Полное условие :
Ваня бегает со скоростью 7 метров в секунду, а Коля пробегает 10 метров за полторы секунды. Кто быстрее и на сколько секунд пробежит дистанцию в 140 метров?

1) 140 : 7 = 20 с - за это время пробежит Ваня 140 м
2) 140 : 10 = 14 раз по 1,5 с - время Коли
3) 14 * 1,5 = 21 с - пробежит Коля 140 м
20 с < 21 с
Ответ: Ваня пробежит 140 м быстрее Коли на 1 с.

Answer 2

Who is faster and by how many seconds will they complete the distance?

To determine who is faster between Vanya and Kolya, we need to compare their speeds and the time it takes for each of them to complete the distance.

Vanya's speed is 7 meters per second, while Kolya's speed is 10 meters in 1.5 seconds.

To calculate the time it takes for each of them to complete the distance, we can use the formula:

Time = Distance / Speed

Let's calculate the time for Vanya first:

Time for Vanya = Distance / Vanya's Speed = Distance / 7

Now, let's calculate the time for Kolya:

Time for Kolya = Distance / Kolya's Speed = Distance / 10

Since we don't have the specific distance mentioned in the question, we cannot determine the exact time it takes for each of them to complete the distance. However, we can compare their speeds and make some observations.

Based on the given speeds, we can see that Kolya is faster than Vanya. Kolya's speed of 10 meters in 1.5 seconds is greater than Vanya's speed of 7 meters per second. Therefore, Kolya will complete the distance faster than Vanya.

Please note that without the specific distance mentioned, we cannot provide the exact time difference between them.
