bookChallenge: Simple Function Creation

Task

Swipe to start coding

You are building a ride-sharing app. Each ride has a distance in kilometers, and you want to calculate the total cost based on a base fare and a per-kilometer rate.

  1. Declare the function calculateTripCost that returns a double.
  2. Add a parameter to the function with type double named distanceKm.
  3. Calculate the total cost by multiplying distanceKm by perKmRate and adding the baseFare.
  4. Return the total cost from the function.

Do not modify the values of baseFare and perKmRate inside the calculateTripCost function.

Example

calculateTripCost(12.5) β†’ 30.0
calculateTripCost(0) β†’ 5.0
calculateTripCost(7) β†’ 19.0
