In this exercise you'll be writing code to analyze the production of an assembly line in a car factory.
The assembly line's speed can range from 0 (off) to 10 (maximum).
At its lowest speed (1), 221 cars are produced each hour.
The production increases linearly with the speed.
So with the speed set to 4, it should produce 4 * 221 = 884 cars per hour.
However, higher speeds increase the likelihood that faulty cars are produced, which then have to be discarded.
You have three tasks.
Implement the (static) AssemblyLine.SuccessRate() method to calculate the ratio of an item being created without error for a given speed.
The following table shows how speed influences the success rate:
0: 0% success rate.1 to 4: 100% success rate.5 to 8: 90% success rate.9: 80% success rate.10: 77% success rate.AssemblyLine.SuccessRate(10)
// => 0.77Implement the (static) AssemblyLine.ProductionRatePerHour() method to calculate the assembly line's production rate per hour, taking into account its success rate:
AssemblyLine.ProductionRatePerHour(6)
// => 1193.4Note that the value returned is a double.
Implement the (static) AssemblyLine.WorkingItemsPerMinute() method to calculate how many working cars are produced per minute:
AssemblyLine.WorkingItemsPerMinute(6)
// => 19Note that the value returned is an int.
