Part 1:

The average number of daily phone calls, C, between two cities varies jointly as the product of their populations,P₁and P₂, and inversely as the square of the distance, d, between them.

1. Calculate the distance in miles between your current city and the capital city of your state. (If you live in the capital of your state, choose a different city in your state to complete the problem.) Use any mapping application (i.e., Google® Maps) to determine this distance.
2. Use a search engine to determine the approximate populations of the two cities.
3. Determine the average number of phone calls between the two cities using the formula above. Show all calculations
