Solution
SPEED = 6 MPH DISK PLOUGH WIDTH = 24 \' . AREA OF FIELD = 1280 ACRES = 1280*43560 SQ.FT= 55756800 SQ.FT LET IT BE OF DIMENSIONS L & B …….L*B = 55756800 SQ.FT TOTAL DISTANCE TO TRAVEL WITH 24 \' DISK PLOUGH =L*B/24 2323200 FEET TOTAL DISTANCE TO TRAVEL WITH 24 \' DISK PLOUGH=2323200/5280= 440 MILES HENCE TIME NEEDED TO PLOUGH WITH 90% EFFICIENCY = 440/(24*0.9)= 20.37037 HRS HENCE TIME NEEDED FOR TURN OVER OF THE FIELD = 20.37037 HRS ANSWER
