Answer 1

1)30+10=40 км/ч 2)120÷40=3 часа

Answer 2

1) 10+30=40 км/ч - скорость сближения 2) 120/40= 3 ч - они встретятся Ответ: через 3 часа

Answer 3

Problem Analysis

We have two individuals, a cyclist and a motorcyclist, who start simultaneously from two different villages that are 120 km apart. The cyclist has a speed of 10 km/h, while the motorcyclist has a speed of 30 km/h. We need to determine how long it will take for them to meet.

Solution

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

Let's calculate the time it takes for each individual to travel the distance between the villages:

- For the cyclist: time = 120 km / 10 km/h = 12 hours - For the motorcyclist: time = 120 km / 30 km/h = 4 hours

Since the motorcyclist is faster, they will reach the meeting point first. The cyclist will take an additional 8 hours to reach the meeting point.

Therefore, the two individuals will meet after 4 hours.

Answer

The cyclist and the motorcyclist will meet after 4 hours.
