Wayne

Wayne can clear a plot of land in 1/3 hours, and Melvin can clear the same plot of land in 2/4 hours. What could possibly be the time for both Wayne and Melvin if they combine to clear the same plot of land?

Correct answer:

t =  0.2 h

Step-by-step explanation:

a=1/3=310.3333 h b=2/4=21=0.5 h  T=1/a+1/b=1/0.3333+1/0.5=5 1/h  t T = 1  t=1/T=1/5=0.2 h
