Jill harvests 1 field/10hrs=1/10 field/hr
Bill harvests 1 field/11hrs=1/11 field/hr
Together they harvest1/10 field/hr+1/11 field/hr=11/110field/hr+10/110 field/hr=21/110 field/hr
1 field/(21/110 field/hr)=5.24 hourANSWER: Together it will take them 5.24 hours to harvest the field.

2 fields + 1/10th of a field harvested in 11hrs
1 field harvested in 11/(2+1/10) = 110/210 = 11/21h
