A car factory takes 6 hours to produce 60 cars. How many hours does the factory take to produce 180 cars?

The production of 180 cars takes 18 hours.

Step-by-step explanation:

Produce cars = 60

Total hours = 6

Production of 60 cars take = 6 hours

Production of 1 car take = 6/60 hours

Production of 180 cars take = 6/60 * 180 hours

=> 6 * 3

=> 18 hours

Therefore, the production of 180 cars takes 18 hours.
