Answer 2

Problem Analysis

We have two boats that start from different docks and move towards each other. The first boat has a speed of 24 km/h and has traveled 96 km until they meet. The second boat has a speed of 30 km/h. We need to find out the distance the second boat has traveled until they meet.

Calculation

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's assume that the time taken for both boats to meet is 't' hours. Since they are moving towards each other, the sum of the distances covered by both boats will be equal to the total distance between the docks.

The distance covered by the first boat is given as 96 km, and its speed is 24 km/h. Therefore, the time taken by the first boat to cover this distance is:

Time taken by the first boat = Distance / Speed = 96 km / 24 km/h = 4 hours

Since both boats are moving towards each other, the total distance between the docks is the sum of the distances covered by both boats. Therefore, the total distance is:

Total distance = Distance covered by the first boat + Distance covered by the second boat

We can rearrange this equation to solve for the distance covered by the second boat:

Distance covered by the second boat = Total distance - Distance covered by the first boat

Substituting the values we have:

Distance covered by the second boat = Total distance - 96 km

Now, we need to find the total distance. Since the boats are moving towards each other, the total distance is the sum of the distances covered by both boats. Therefore:

Total distance = Distance covered by the first boat + Distance covered by the second boat

Substituting the values we have:

Total distance = 96 km + Distance covered by the second boat

Now we can substitute this expression for the total distance into the equation for the distance covered by the second boat:

Distance covered by the second boat = (96 km + Distance covered by the second boat) - 96 km

Simplifying this equation, we find:

Distance covered by the second boat = Distance covered by the second boat

This means that the distance covered by the second boat is equal to the distance covered by the second boat. In other words, the distance covered by the second boat until they meet is equal to the distance covered by the first boat until they meet, which is 96 km.

Therefore, the second boat has traveled 96 km until they meet.

Answer

The second boat has traveled a distance of 96 km until they meet the first boat.
