Code:

 
10 yr      = 9 yr 12 mo
-4 yr 4 mo =-4 yr  4 mo

19ft-1ft 9 in

a)8ft 9 in

Code:

 
19 ft        = 18 ft 12 in
-1 ft 9 in   -  1 ft  9 in
-------------------------
               17 ft  3 in 
 
I don't see this answer as a choice.  Maybe you meant to use 10 ft instead of 19 ft.  If you did, the answer would be (d).

Sorry, I don't know what you mean by this one.

$\frac{36960 ft}{1}\cdot\frac{1 mi}{5280ft}=\frac{36960}{5280}=?$
