Calculation:  Let the time to fill an order working together be x.  Then Janet and Jim fill an order at the rate of 1x per hour.  Given that, Janet can fill an order in 2 hours, then he can fill an order at the rate of 12 per hour.  Given that, Jim can fill an order in 3 hours, then he can fill an order at the rate of 13 per hour.  From the given information, we can form an equation as follows,  12+13=1x  Solving the above equation,  3+26=1x  56=1x  x=65  x=1.2 hours  Therefore, the time to fill an order working together is 65 hours or 1.2 hours.
