It takes my Father 3 hours to plow the our cornfield with his new tractor.
Using the old tractor it takes me 5 hours.
If we both plow for 1 hour before I go to school,how long will it take him to finish
:
let t = time Dad plows after he goes to school
:
Let the completed job = 1; (a plowed field)
:
A shared work equation
%28%28t%2B1%29%29%2F3 + 1%2F5 = 1
Multiply by 15, results
5(t+1) + 3 = 15
5t + 5 + 3 = 15
5t = 15 - 8
t = 7%2F5
ANSWER
t = 1.4 hrs or 1 + .4(60) = 1 hr 24 more minutes to finish
hope this helps :)

Answer:
300 Square feet
Step-by-step explanation:
Susan built a rectangular fence around her swimming pool.
Length=15ft
Width(or Breadth)=10ft
Height=6ft
To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.
Surface Area of a Cuboid= 2(LW+LH+WH)
However since the top and bottom are open, the Surface Area becomes
Surface Area of the fence= 2(LW+WH)
=2((15X6)+(10X6)
=2(90+60)=2 X 150 =300
Susan uses 300 Square feet to build her fence.
