It takes 25 men to build a wall in 4 hours . How long does it take 100 men to build the same wall

1 hour

Step-by-step explanation:

100 is 4 times more than 25.

1 hours

Step-by-step explanation:

By concept we know it takes a person to complete a job of three person more time. so we shall multiply in this question.

if 25 men takes 4 hours

1 men will take 4 * 25 = 100 hours

100 men takes = ( 100 ÷ 100 ) hours = 1 hours

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
