Explanation:

Step1: Determine Latitude Difference

First, find the latitude difference between Red Bank and Belleville. Red Bank is at \(15^\circ\) S (assuming the bottom is south, looking at the labels like \(15^\circ\) S, \(20^\circ\) S), and Belleville is at \(20^\circ\) S? Wait, no, looking at the map, the latitude lines: Red Bank is near \(15^\circ\) S? Wait, maybe the vertical lines are longitude (E) and horizontal are latitude (S, since the labels are \(10^\circ\) S, \(15^\circ\) S, \(20^\circ\) S). Wait, Red Bank is at a latitude (horizontal) and Belleville is at a lower latitude (more south, higher degree S). Wait, actually, to calculate distance on a map, we can use the fact that 1 degree of latitude is about 111 km. Let's check the latitude difference. Red Bank: let's see the horizontal lines. Red Bank is at, say, \(15^\circ\) S, Belleville at \(20^\circ\) S? Wait, no, looking at the map, the distance between Red Bank and Belleville: let's count the latitude degrees. Wait, maybe the vertical lines (longitude) are \(30^\circ\) E, \(35^\circ\) E, \(40^\circ\) E, \(45^\circ\) E, \(50^\circ\) E. Horizontal lines (latitude) \(10^\circ\) S, \(15^\circ\) S, \(20^\circ\) S. Red Bank is at \(15^\circ\) S (horizontal line), Belleville is at \(20^\circ\) S? Wait, no, Red Bank's latitude: looking at the map, Red Bank is on a horizontal line, and Belleville is on a lower horizontal line (more south, so higher S degree). Wait, the difference in latitude: let's say Red Bank is at \(15^\circ\) S, Belleville at \(20^\circ\) S? No, maybe the other way. Wait, actually, the key is that 1 degree of latitude is approximately 111 kilometers. Let's find the number of degrees between Red Bank and Belleville. Looking at the map, the vertical (longitude) lines are spaced 5 degrees apart (30 - 35, 35 - 40, etc.), horizontal (latitude) lines 5 degrees? Wait, no, the latitude labels: \(10^\circ\) S, \(15^\circ\) S, \(20^\circ\) S. So each horizontal line is 5 degrees of latitude. Wait, Red Bank is at \(15^\circ\) S (middle horizontal line), Belleville is at \(20^\circ\) S (lower horizontal line). So the difference is \(20^\circ - 15^\circ = 5^\circ\) of latitude? Wait, no, maybe longitude? Wait, no, latitude is north-south, longitude east-west. Wait, the map has a north arrow, so up is north, so down is south. So Red Bank is above Belleville (more north, lower S degree), Belleville is below (more south, higher S degree). So the latitude difference: let's say Red Bank is at \(15^\circ\) S, Belleville at \(20^\circ\) S, so difference is \(5^\circ\) of latitude. Then, distance = degrees × 111 km/degree. So \(5^\circ \times 111 \text{ km/}^\circ = 555 \text{ km}\). But maybe the scale is different. Wait, alternatively, if we use the map's scale, but since it's not given, we use the latitude/longitude method. Wait, another way: 1 degree of latitude ≈ 111 km. So if the difference is 5 degrees, 5×111=555 km. But maybe the actual difference is 2 degrees? Wait, no, looking at the map, Red Bank and Belleville: let's count the latitude lines. Red Bank is on the \(15^\circ\) S line? Wait, the labels are \(10^\circ\) S, \(15^\circ\) S, \(20^\circ\) S. So between \(15^\circ\) S and \(20^\circ\) S is 5 degrees. So distance is approximately 5×111=555 km, or maybe 2 degrees? Wait, no, maybe I misread. Wait, the problem is "about how far", so approximate. Alternatively, if the longitude difference? No, latitude is north-south. Wait, maybe the map has a scale, but since it's not provided, we use the standard 1° latitude ≈ 111 km. Let's check the positions: Red Bank is at a latitude, Belleville at a lower latitude (more south). The difference in latitude: let's say from \(15^\circ\) S to \(20^\circ\) S is 5 degrees, so 5×111=555 km. But maybe the answer is around 500 km or 600 km. Alternatively, maybe the longitude? No, longitude distance depends on latitude. Wait, maybe the map is using a different scale, but since we have to estimate, using latitude difference. So step 1: find latitude difference. Step 2: multiply by 111 km/degree.

Step1: Identify Latitude Positions

Red Bank is near \(15^\circ\) S, Belleville near \(20^\circ\) S.
Latitude difference: \(20^\circ - 15^\circ = 5^\circ\).

Step2: Calculate Distance

1° latitude ≈ 111 km.
Distance = \(5^\circ \times 111 \text{ km/}^\circ = 555 \text{ km}\) (approximate).

Answer:

About 550 - 600 kilometers (e.g., 555 km, or a rounded estimate like 500 - 600 km; precise calculation gives ~555 km).
