You can put this solution on YOUR website! 8 men take 10 hrs to build a brick wall
---------------------------------
3 times as many men will take 1/3 that time, so
24 men take take 3 hrs and 20 min ( 3 1/3 hrs )
-----------------------------------------
1/8 that number of men take 8 times longer, so
3 men take ( 3 hrs and 20 min ) x 8 = 24 hrs and 160 min
( 160 min = 2 hrs 40 min )
( 24 hrs + 2 hrs + 40 min )
It will take 3 men 26 hrs and 40 min
to build the brick wall
