Answer 2

Calculating the Distance Between the Docks

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

distance = speed * time

Let's calculate the distance using the given information.

The first boat's speed is 15 km/h, and the second boat's speed is 18 km/h. They meet after 3 hours.

Calculations:

- Distance covered by the first boat = 15 km/h * 3 h = 45 km - Distance covered by the second boat = 18 km/h * 3 h = 54 km

The distance between the docks is the sum of the distances covered by each boat.

Result:

The distance between the docks is 45 km + 54 km = 99 km.
