Question

One gardener can mow a golf course in 4 hours, while another gardener can mow the same golf course in 6 hours. How long would it take if the two gardeners worked together to mow the golf course?

Answer 1

Answer:

2 hours and 24 minutes

Step-by-step explanation:

1/4 +1/6=1/t

12t(1/4+1/6)=12t(1/t)

3t+2t=12

t=2.4 hours or 2 hours and 24 minutes
