A helicopter company charges $85 for the first kilometer of a trip and $5 every kilometer after that. If the total cost of a trip was $365, how many kilometers were flown?

To determine the total number of kilometers flown, let's break the problem into manageable steps.

Step 1: Understand the cost structure

• The first kilometer costs $85.
• Every subsequent kilometer costs $5 each.

Step 2: Subtract the cost of the first kilometer

The total cost of the trip is $365. Subtract the cost of the first kilometer:

Step 3: Calculate the number of subsequent kilometers

Each subsequent kilometer costs $5. The number of kilometers flown after the first kilometer is:

Step 4: Add the first kilometer

Including the first kilometer, the total distance flown is:

Final Answer:

The helicopter flew 57 kilometers.
