(ii) The Central Water Authority wants to lay on a water supply to caravans positioned in different regions of the country specifically at Albion, Bagatelle, Curepipe, Dagotire, Ebene, Moka and Plaine Magnien. The distances in kilometers between each region are shown in Table 1. Table 1: Distances in kilometers.
