Problem Analysis

We are given that a boat travels from one dock to another at a speed of 30 km/h and returns at a speed 10 km/h faster. We need to find the total time it takes for the boat to complete the round trip if the distance between the docks is 240 km.

Solution

Let's break down the problem into two parts: the time taken for the boat to travel from one dock to another and the time taken for the boat to return.

1. Time taken for the boat to travel from one dock to another: - Speed of the boat = 30 km/h - Distance between the docks = 240 km - Using the formula `time = distance / speed`, the time taken for the boat to travel from one dock to another is: 240 km / 30 km/h = 8 hours.

2. Time taken for the boat to return: - Speed of the boat = 30 km/h + 10 km/h = 40 km/h (10 km/h faster than the speed while going) - Distance between the docks = 240 km - Using the formula `time = distance / speed`, the time taken for the boat to return is: 240 km / 40 km/h = 6 hours.

3. Total time taken for the round trip: - The boat takes 8 hours to travel from one dock to another and 6 hours to return. - Therefore, the total time taken for the round trip is: 8 hours + 6 hours = 14 hours.

So, the boat will take 14 hours to complete the entire round trip.

Answer

The boat will take 14 hours to complete the entire round trip from one dock to another and back.
