Short Answer 
The total population of the four provinces is 9,875,845, with Pichincha having the highest population at 4,391,923. Roberto’s total travel distance between the locations is 1,017.2 kilometers.
Step 1: Calculate Total Population
First, you need to gather the population data for each of the four provinces. Here are the populations:
- Provincia: 3,089,473
- Manabí: 1,592,840
- Azuay: 801,609
- Pichincha: 4,391,923
Next, add these numbers together to find the total population: 3,089,473 + 1,592,840 + 801,609 + 4,391,923 = 9,875,845 inhabitants in total.
Step 2: Identify Highest Population Province
Now, analyze the population figures to determine which province has the highest population. Here’s a comparison of the populations:
- Provincia: 3,089,473
- Manabí: 1,592,840
- Azuay: 801,609
- Pichincha: 4,391,923
From this comparison, it is clear that Pichincha has the highest population with 4,391,923 inhabitants.
Step 3: Calculate Total Travel Distance
Finally, calculate the total distance Roberto travels on his journey. The distances for each leg of the journey are as follows:
- From Guayaquil to Manabí: 195.8 km
- From Manabí to Quito: 402.9 km
- From Guayaquil to Quito: 418.5 km
By adding these distances together, you find that Roberto travels a total of 1,017.2 kilometers on his complete route.
