8585 inches per minute

Explanation:

1212 inches =1=1 foot and 6060 minutes =1=1 hour

So:

(425 ft)/(1 hr)xx(1 hr)/(60 m)xx(12 i)/(1 ft)425ft1hr×1hr60m×12i1ft

Cancel units:

(425 cancel(ft))/(1 cancel(hr))xx(1 cancel(hr))/(60 m)xx(12 i)/(1 cancel(ft))

Multiply across:

(425 xx 12 i)/(60 m)=(5100 i)/(60 m)=85 inches per minute
