Harvester

Harvester has cutting width 4 m and harvested grain in the field, which is 87 meters wide. Harvester moves along the length of the field for six minutes, going back (without cutting) it takes half the time. Each turn at the end field take one minute. How many hours and minutes is needed to harvest whole field?

Result

h = 3:13 hh:mm Wrong answer

Solution:

h=((87/4) (6+6/3+1)6/31)/60=25780=3.2125=3:13 hh:mmh=((87/4) \cdot \ (6+6/3+1)-6/3-1)/60=\dfrac{ 257 }{ 80}=3.2125=3:13 \ \text{hh}:\text{mm}
