Question

Два грибника едут навстречу друг другу на велосипедах: один с корзиной грибов на рынок, а другой, уже с пустой корзиной, обратно. Первый грибник едет со скоростью 14 км/ч, а другой - со скоростью 12 км/ч. В какой-то момент времени расстояние между ними было равно 8 км. Какое расстояние было между ними спустя 1 час? Рассмотри два случая.

Answer 1

Вот объяснение, надеюсь всё понятно

Answer 2

To solve this problem, we can use the formula: distance = speed × time. Let's consider two cases:

Case 1: The first mushroom picker is going to the market, and the second one is returning.

In this case, the first mushroom picker is traveling at a speed of 14 km/h, and the second mushroom picker is traveling at a speed of 12 km/h. At a certain moment, the distance between them is 8 km.

To find the distance between them after 1 hour, we can calculate the distance traveled by each mushroom picker in 1 hour and subtract the two distances.

The distance traveled by the first mushroom picker in 1 hour is 14 km (14 km/h × 1 h = 14 km).

The distance traveled by the second mushroom picker in 1 hour is 12 km (12 km/h × 1 h = 12 km).

Therefore, the distance between them after 1 hour can be calculated as follows: Distance = 8 km + (14 km - 12 km) = 8 km + 2 km = 10 km.

Case 2: The first mushroom picker is returning, and the second one is going to the market.

In this case, the first mushroom picker is traveling at a speed of 12 km/h, and the second mushroom picker is traveling at a speed of 14 km/h. At a certain moment, the distance between them is 8 km.

Using the same approach as in Case 1, we can calculate the distance between them after 1 hour.

The distance traveled by the first mushroom picker in 1 hour is 12 km (12 km/h × 1 h = 12 km).

The distance traveled by the second mushroom picker in 1 hour is 14 km (14 km/h × 1 h = 14 km).

Therefore, the distance between them after 1 hour can be calculated as follows: Distance = 8 km + (12 km - 14 km) = 8 km - 2 km = 6 km.

So, in Case 1, the distance between them after 1 hour is 10 km, and in Case 2, the distance between them after 1 hour is 6 km.
