Distance Calculation Between Ports

To calculate the distance between ports A and B, and ports B and C, we can use the given information. The distance from A to B is 30 km, and the distance from B to C is 7 km 650 m. Additionally, it's mentioned that the distance between A and B is twice the distance between B and C.

Calculating the Distance

Let's denote the distance between A and B as x and the distance between B and C as y.

Given: - Distance from A to B (x) = 30 km - Distance from B to C (y) = 7 km 650 m - The distance between A and B is twice the distance between B and C: x = 2y

We can use this information to solve for the values of x and y.

Solution

We know that the distance between A and B is twice the distance between B and C, so we can express this as an equation: x = 2y

Given that x = 30 km, we can substitute this value into the equation: 30 = 2y

Solving for y: y = 30 / 2 y = 15 km

So, the distance between B and C (y) is 15 km.

Conclusion

The distance between the ports B and C is 15 km.
