The area of the fence is 6*25=150 square feet.
It will take him 150 / 2 = 75 of 10-minute intervals. 75 min *10 = 750 min = 750/60 hours = 12.5 hours.

Ratio and proportion                  fence area= 6 x 25= 150 sq ft
2 ft/ 10 min= 150 sq ft/ x min
2 x=1500
     x= 750 min
convert to hours divide by 60

  x= 12.5 hours

hope this helps
