Question

If it takes 4 people 4 days to dig a hole, how long does it take 2 people to dig a half-hole

Answer 1

the answer is 4 days. because if 2 people were digging a whole hole, it would take twice as long, being 8 days. digging half a hole, you would just cut the 8 in half, leaving 4 days for 2 people to dig half a hole.
