120 men working 9 hours a day can construct a road in 40 days. how long would it take to construct the same road if 150 men work 6 hours a day on it?

This is a question from Ratio and Proportion based concept.

120 men working for 9 hours a day, construct a road in 40 days. We are required to calculate the number of days to construct the road if 150 people work for 6 hours.

Let's assume the number of days taken for constructing is 'x'.

So normally we take 2 ratios and obtain the unknown value by cross multiplication.

Applying the same approach we get:

Since the first two fractions are inversely related, we multiply the numerators and denominators respectively.

Hence we get:

Hence it takes 33.33 days for 150 men to construct the road working for 6 hours each day.

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
