Question

Два велосипедиста выехали одновременно навстречу друг другу.Скорость одного 14 км/ч а другово 16км/ч.Встретятся ли велосипедисты через час если расстояние между ними 40км?

Answer 1

14+16=30 (км/ч) скорость сближения
40:30=4/3=1 1/3 (ч) через 1 1/3 часа они встретятся
1 1/3-1=1/3 (ч)
Ответ: через час они не встретятся, им не хватит 1/3 часа (20 минут)

Answer 2

14 + 16 = 30 км
30 < 40
Ответ: нет.

Answer 3

Problem Analysis

Two cyclists are traveling towards each other. The first cyclist's speed is 14 km/h, and the second cyclist's speed is 16 km/h. The distance between them is 40 km. We need to determine if they will meet after one hour.

Solution

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

Let's calculate the distance each cyclist will cover in one hour.

The first cyclist's distance covered in one hour: distance = speed * time distance = 14 km/h * 1 h distance = 14 km

The second cyclist's distance covered in one hour: distance = speed * time distance = 16 km/h * 1 h distance = 16 km

Now, let's calculate the total distance covered by both cyclists in one hour.

Total distance covered in one hour = 14 km + 16 km Total distance covered in one hour = 30 km

Conclusion

The total distance covered by both cyclists in one hour is 30 km, which is less than the initial distance between them (40 km). Therefore, the cyclists will not meet after one hour.
