To determine the required speed, we first need to find the total displacement from Mbale (M) to Gulu (G) by breaking down each leg of the journey into its East-West (x) and North-South (y) components.

To determine the required speed, we first need to find the total displacement from Mbale (M) to Gulu (G) by breaking down each leg of the journey into its East-West (x) and North-South (y) components. We will use the convention that East is positive x, North is positive y, and bearings are measured clockwise from North.
The components are calculated as:
$x = \text{distance} \times \sin(\text{bearing})$
$y = \text{distance} \times \cos(\text{bearing})$

Step 1: Calculate the components for the first leg (Mbale to Juba).
Distance $d_1 = 370 \text{ km}$, Bearing $\theta_1 = 305^\
