Awall can be built by 6 men working 8 hours per day in 5 days. how many days will it take 4 men to build the same wall if they worked only 5 hours per day? ?

Total number of working hours = 6x8x5 = 240 hours 

Let x be the number of days required 

240 = 4(5)(x) 

x = 12 days

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

because they could drop even lower..
