Final answer:
The urban geographer will spend 24 divided by (x + 12), where x is the number of cities in Brazil, days in each city throughout her trip.
Step-by-step explanation:
The question involves finding out how many days an urban geographer will spend in each city during her trip to Brazil and Canada. She is visiting a certain number of cities in Brazil (let's denote this number as x) and 12 cities in Canada. The total number of days for the visits is 24 days, and the geographer plans to spend an equal number of days in each city. To find the number of days spent in each city, we need to divide the total number of days by the total number of cities visited.
First, we add the number of cities in Brazil (x) and the number of cities in Canada (12) to find the total number of cities visited. The sum is x + 12. Then, we divide the 24 days by the total number of cities x + 12 to find the number of days spent in each city:
Days spent in each city = Total days / Total number of citiesDays spent in each city = 24 / (x + 12)
