If it takes 2 men 40 min to dig the garden,
it will take half as many men twice as long, so
---------------------------------------
It takes 1 man 80 min to dig the garden
----------------------------------------
It will take 8 men 1/8 of this time to dig the garden, so
------------------------------------------------
I takes 8 men +%281%2F8%29%2A80+=+10+ min to dig the garden
