Multiple Parameters

That determines if a race car driver can proceed to the next round of qualifications given their current performamnce. 
Since this depends on 2 different types of data, the driver's speed and state of the car, we can set up multiple parameters in a function:

Code:

func didQualify(slowestDriver: Bool, retired: Bool) -> String {

  if slowestDriver || retired {
    return "Eliminated"
  } else {
    return "Qualified"
  }
}

Observations:
1. slowestDriver and retired are parameters of type Bool within the function, didQualify(slowestDriver:retired:) that returns a String Value.
2. The parameters are used in an if/else statement to determine whether or not the driver continues onto the next round.

The if statement executes within the function with the boolean values, and the function returns "Eliminated".

Problem Statement:
Set up a function timeToDestination(), that will use an airplane's speed

timeToDestination() should accept distance and speed parameters of type Int()
timeToDestination()

EXAMPLE:

func timeToDestination(distance: Int, speed: Int) -> Int{
    let time = distance/speed
    return time
}

print(timeToDestination(distance: 6836, speed: 560))

print("Time to reach New York will be \(timeToDestination(distance: 6836, speed: 560)) hours")

Output:

12
Time to reach New York will be 12 hours
