# Hints ## 1. Calculate the success rate - You need to translate the speed into a success rate, using the rules given in the instructions. - The returned value is a floating-point number. - Julia does not have the `select`/`case` syntax present in some other languages, but the Introduction discussed `if-else` syntax. ## 2. Calculate the production rate per hour - The total theoretical production rate depends on the base production rate (a constant) and the speed. - Return the actual production rate, which also depends on the success rate. ## 3. Calculate the number of working items produced per minute - The hourly production rate was calculated in task 2. - This task requires the rate per minute. - Only complete, working cars are counted in this exercise, so you will need to remove part-complete cars from the count. - The return value must be an integer (for example `7`, not `7.0`). - The [Numbers][numbers] Concept already discussed ways to round values.
