B) Calculate the average price per kilometer for all cities.
C) Identify the city with the highest price.
D) Calculate the total cost of a round-trip ticket to Chicago.

Answer 1

San Diego has the lowest price per kilometer, the average price per kilometer for all cities is $0.08, Los Angeles has the highest price, and the total cost of a round-trip ticket to Chicago is $600.00.

Step-by-step explanation:

To determine the city with the lowest price per kilometer, divide the price by the distance for each city. The city with the lowest result is San Diego, with a price per kilometer of $0.06.

To calculate the average price per kilometer for all cities, add up the prices and divide by the total distance. The average price per kilometer is $0.08.

The city with the highest price is Los Angeles, with a price per kilometer of $0.11.

To calculate the total cost of a round-trip ticket to Chicago, multiply the price per kilometer of Chicago ($0.10) by the distance to Chicago (3000 km) and then multiply by 2. The total cost is $600.00.
