Puzzle 7 


I recently asked my friend Alex to buy me some ribbon for my child's bonnet.

Alex went to the haberdashery shop for the required length, but accidentally swapped the feet and inches.

When I measured the resulting ribbon, I only had 5/8 of the length I required.

How much ribbon did I originally ask for?

Remember that there are 12 inches in a foot.
