Final answer:
The tire factory produces 9 sets of tires in three-quarters of an hour, with each set containing 4 tires, resulting in a total of 36 tires.
Step-by-step explanation:
The question concerns how many tires are produced in three-quarters of an hour by a factory that produces a set of 4 tires every 5 minutes. To find the answer, we can calculate the number of 5-minute intervals in three-quarters of an hour. Three-quarters of an hour is 45 minutes. There are 45 minutes / 5 minutes per set = 9 sets of tires. Since each set contains 4 tires, we multiply the number of sets by 4 to get the total number of tires: 9 sets × 4 tires per set = 36 tires.
