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 success_rate() 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.success_rate(10)
# => 0.77Implement the production_rate_per_hour() method to calculate the assembly line's production rate per hour, taking into account its success rate:
production_rate_per_hour(6)
# => 1193.4Note that the value returned is a double.
Implement the working_items_per_minute() method to calculate how many working cars are produced per minute:
working_items_per_minute(6)
# => 19Note that the value returned is an integer: incomplete items are not included.
