Answer 1

The correct option is A $63,409\text{inch}$


To find the sum of $1\text{mile}+1\text{yard}+1\text{feet}+1\text{inch}$
Convert all the other units to inches.


We know:
$1\text{yard}=36\text{inch}$
$1\text{feet}=12\text{inch}$
$1\text{mile}=1760\text{yards}=1760\times 36\text{inches}=63,360\text{inch}$
Put all these values in the equation:
$1\text{mile}+1\text{yard}+1\text{feet}+1\text{inch}$
$\Rightarrow 63,360\text{inch}+36\text{inch}+12\text{inch}+1\text{inch}$
$\Rightarrow 63,409\text{inch}$
Hence, $1\text{mile}+1\text{yard}+1\text{feet}+1\text{inch}=63,409\text{inch}$
