Answer 1

Answer:

ALWAYS start by visualizing the problem.

Picturing 39 people might be difficult, but you can picture 3–5 people, cooperating on one little section of road, right? Watch a little time-lapse in your head. Over 5 hours, they get a certain amount of work done. Figure that happens many times over, as you have many such squads.

Okay, now remove a couple of those 3–5 person squads, but make them spend an extra hour that day.

Uh-oh! According to local labor law, they now need a paid lunch break!

Oh, hey, fixing a road is hard work. The workers are tired by the time they get into the sixth hour of the day.

Wait, for some reason, with fewer people on the task they worked faster (because it’s less crowded) or slower (because they had a special time-saving machine that can only be operated with exactly 39 people).

Maybe these bullets are true, or maybe they aren’t. Since the question doesn’t say one way or other, you need to make assumptions.

Answer 2

The answer should.be that the worker worked 10
