Question

Из посёлка А выехал велосипедист со скоростью 15км/ч. А из посёлка В навстречу выехал второй велосипедист со скоростью 20км/ч. Какого расстояние между посёлками если через 3 часа они встретились

Answer 1

20*3=60км/ч
15*3=45км/ч
60+45=105км

Answer 2

Problem Analysis

We are given that two cyclists start from two different villages, A and B, and are moving towards each other. The first cyclist starts from village A with a speed of 15 km/h, while the second cyclist starts from village B with a speed of 20 km/h. We need to find the distance between the two villages if they meet after 3 hours.

Solution

To find the distance between the two villages, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each cyclist and then find the total distance between the villages.

1. The first cyclist travels at a speed of 15 km/h for 3 hours. Therefore, the distance traveled by the first cyclist is:

Distance1 = Speed1 x Time = 15 km/h x 3 h = 45 km 2. The second cyclist travels at a speed of 20 km/h for 3 hours. Therefore, the distance traveled by the second cyclist is:

Distance2 = Speed2 x Time = 20 km/h x 3 h = 60 km 3. The total distance between the villages is the sum of the distances traveled by each cyclist:

Total Distance = Distance1 + Distance2 = 45 km + 60 km = 105 km

Therefore, the distance between the villages is 105 km.

Answer

The distance between the villages is 105 km.
