Answer 2

Problem Analysis

We have two boats that start from two different piers and move towards each other. We are given the speeds of both boats and the time it takes for them to meet. We need to find the distance between the two piers.

Solution

To find the distance between the two piers, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by each boat and then add them together to find the total distance between the piers.

Calculation

The speed of the first boat is given as 15 km/h, and the speed of the second boat is given as 18 km/h. The time it takes for them to meet is given as 3 hours.

The distance traveled by the first boat is: distance = speed * time = 15 km/h * 3 hours = 45 km.

The distance traveled by the second boat is: distance = speed * time = 18 km/h * 3 hours = 54 km.

The total distance between the two piers is the sum of the distances traveled by each boat: 45 km + 54 km = 99 km.

Therefore, the distance between the two piers is 99 km.

Conclusion

The distance between the two piers is 99 km.
