Question

Two companies working together can clear a parcel of land in 30 hours. Working alone, it would take company A 3 hours longer to clear the land than it would Company B. How long would it take Company B to clear the parcel of land alone?

Answer 1

12 hours. Because half of 30 is 15 and if company A is taking three hours longer, you take 3 hours of company “B” that would make a total of 12 hours because 15-3=12
