Explanation:

Step1: Define directions

Let north be positive and south be negative.

Step2: Calculate the sum

The first vector is \( + 125\) (north) and the second is \( - 32\) (south). The sum is \(125+( - 32)=125 - 32\).

$$125-32 = 93$$

Since the result is positive, the direction is north.

Answer:

93 km north
