Question

Из деревни выехал велосипедист со скоростью 7 км/ч. Когда он проехал 21 км, из той же деревни в противоположном направлении выехал второй велосипедист со скоростью 10 км/ч. Какое время был в пути каждый велосипедист, Конда расстояние между ними стало 782 км.

Answer 1

(782-21)/(10+7)=44.765ч(немного округленные значение, т.к. целого не получается)-был в пути второй велосипедист
44.765+3=47.765ч- был в пути первый

Answer 2

Problem Analysis

We are given that a cyclist leaves a village at a speed of 7 km/h. After traveling 21 km, another cyclist leaves the same village in the opposite direction at a speed of 10 km/h. We need to find the time it takes for each cyclist to travel until the distance between them becomes 782 km.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for the first cyclist to travel 21 km at a speed of 7 km/h: time1 = 21 km / 7 km/h = 3 hours.

Now, let's calculate the time it takes for the second cyclist to travel a distance of 782 km at a speed of 10 km/h: time2 = 782 km / 10 km/h = 78.2 hours.

Therefore, the first cyclist was in transit for 3 hours, while the second cyclist was in transit for 78.2 hours.

Answer

The first cyclist was in transit for 3 hours, and the second cyclist was in transit for 78.2 hours.

Note: The above solution assumes that the second cyclist continues to travel at a constant speed of 10 km/h until the distance between them becomes 782 km.
