Answer 2

Problem Analysis

We are given two points, A and B, with a distance of 28 km between them. Two cars start simultaneously from these points and move towards each other. One car arrives at point B 16 minutes after the meeting, while the other car arrives at point A 9 minutes after the meeting. We need to find the speed of each car.

Solution

Let's assume the speed of the car that starts from point A is v1 km/min, and the speed of the car that starts from point B is v2 km/min.

To find the speed of each car, we can use the formula:

Speed = Distance / Time

Since the distance between the two points is 28 km, the time taken by the first car to reach point B is 16 minutes, and the time taken by the second car to reach point A is 9 minutes, we can set up the following equations:

v1 = 28 / 16 v2 = 28 / 9 Now, let's calculate the speeds of the two cars.

Calculation

Using the above equations, we can calculate the speeds of the two cars:

v1 = 28 / 16 = 1.75 km/min v2 = 28 / 9 ≈ 3.11 km/min

Therefore, the speed of the car that starts from point A is approximately 1.75 km/min, and the speed of the car that starts from point B is approximately 3.11 km/min.

Please note that these values are approximate and rounded to two decimal places.
