Answer 3

Calculation of the Distance Between the Piers

To find the distance between the piers, we can use the formula:

Distance = Speed × Time

Given that the first boat has a speed of 15 km/h and the second boat has a speed of 18 km/h, and they meet after 3 hours, we can calculate the distance between the piers.

Using the formula, we have:

Distance = Speed × Time

For the first boat: Distance1 = 15 km/h × 3 hours

For the second boat: Distance2 = 18 km/h × 3 hours

Adding the distances together, we get:

Total Distance = Distance1 + Distance2

Let's calculate the distance using the given information.

Distance1 = 15 km/h × 3 hours = 45 km Distance2 = 18 km/h × 3 hours = 54 km

Total Distance = Distance1 + Distance2 = 45 km + 54 km = 99 km

Therefore, the distance between the piers is 99 kilometers.
