Question

If it took eight men ten hours to build a wall, how long will it take four men?

Answer 1

Since it took 10 hours for 8 men to build a wall. If you had 4 men build a wall it would most likely take twice as long than if there were 8 men due to less people.

So it would take 20 hours for 4 men to build a wall.

Answer 2

I want to say 20

Explanation:

4 is half of 8, so double the time and its 20.........
