Question 36645
This answer is NOT correct.  Since both accountants working together can finish the job in 6 hours, the proper format for this equation is 1/Accountant A's time + 1/Accountant B's time =1/6.  Since B=2A (Accountant B is 1/2 as fast as Accountant A) the right equation reads: 1/A + 1/2A = 1/6.  Solving for A we get
A=9; and thus B=2A=18.  Check our work: 1/9+1/18=1/6.
