Problem Analysis

We have two cars traveling towards each other from two different points. The first car takes 3 hours to cover the distance, while the second car takes 6 hours. We need to determine how many hours it will take for the cars to meet.

Solution

To find the time it takes for the cars to meet, we can use the formula:

Time = Distance / Speed

Let's assume the distance between the two points is D. The first car's speed is S1 (which we need to find), and the second car's speed is S2 (which we also need to find).

We know that the first car takes 3 hours to cover the distance, so we can write the equation:

D = S1 * 3 Similarly, the second car takes 6 hours to cover the distance, so we can write the equation:

D = S2 * 6 To find the time it takes for the cars to meet, we need to find the distance D first. We can do this by equating the two equations:

S1 * 3 = S2 * 6

Now, we can solve this equation to find the values of S1 and S2. Once we have the speeds, we can calculate the time it takes for the cars to meet by dividing the distance D by the sum of the speeds (S1 + S2).

Let's solve the equation to find the speeds S1 and S2:

S1 * 3 = S2 * 6

Dividing both sides by 3:

S1 = 2S2

Now, we can substitute this value of S1 into equation:

D = 2S2 * 3

Simplifying:

D = 6S2

Now, we can substitute this value of D into equation:

6S2 = S2 * 6

Simplifying:

6S2 = 6S2

This equation is true for any value of S2. Therefore, we can conclude that the speeds of the two cars can be any value as long as they satisfy the equation S1 = 2S2.

To find the time it takes for the cars to meet, we need to divide the distance D by the sum of the speeds (S1 + S2). Since we don't have the actual values of D, S1, and S2, we cannot determine the exact time it takes for the cars to meet.

However, we can conclude that the time it takes for the cars to meet will be less than or equal to 3 hours, as the first car takes 3 hours to cover the distance.
