Answer 2

Problem Analysis

To solve this problem, we need to find the speed of the river's current. We are given the following information: - The boat traveled for 4 hours. - The distance between the two ports is 64 km. - The boat's speed is 14 km/h.

Let's assume the speed of the river's current is represented by x km/h.

Solution

To find the speed of the river's current, we can use the formula:

Distance = Speed x Time

The boat's speed is the sum of its own speed and the speed of the river's current. Therefore, we can write the equation as:

64 km = (14 km/h + x km/h) x 4 hours

Let's solve this equation to find the speed of the river's current.

Calculation

To solve the equation, we can start by simplifying it:

64 km = (14 km/h + x km/h) x 4 hours

64 km = (14 + x) km/h x 4 hours

Now, we can multiply both sides of the equation by 4 hours to eliminate the time:

256 km/hours = (14 + x) km/h x 4 hours

Next, we can divide both sides of the equation by 4 hours to isolate the speed:

256 km/hours ÷ 4 hours = (14 + x) km/h

64 km/h = 14 km/h + x km/h

Finally, we can subtract 14 km/h from both sides of the equation to find the speed of the river's current:

64 km/h - 14 km/h = x km/h

50 km/h = x km/h

Answer

Therefore, the speed of the river's current is 50 km/h.
