2) 40 метров.

Answer 2

Problem Statement

Two objects, A and B, start moving towards each other from points A and B with speeds of 1 m/s and 2 m/s, respectively. The distance between points A and B is 120 m. We need to determine: 1) The time it takes for the objects to meet. 2) The distance from point A to the meeting point.

Solution

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

1) To find the time it takes for the objects to meet, we need to calculate the relative speed of the objects. The relative speed is the sum of the speeds of the two objects since they are moving towards each other. In this case, the relative speed is 1 m/s + 2 m/s = 3 m/s.

Using the formula, we can calculate the time it takes for the objects to meet: time = distance / relative speed = 120 m / 3 m/s = 40 seconds. Therefore, it will take 40 seconds for the objects to meet.

2) To find the distance from point A to the meeting point, we can use the formula: distance = speed * time.

Since the speed of object A is 1 m/s and the time it takes for the objects to meet is 40 seconds, we can calculate the distance from point A to the meeting point: distance = speed * time = 1 m/s * 40 s = 40 meters. Therefore, the distance from point A to the meeting point is 40 meters.

In summary: 1) The objects will meet after 40 seconds. 2) The distance from point A to the meeting point is 40 meters.
