How you mean the rate is uncertain. The assumption made will be r is the one-man rate and that twice
the number of men would be used to make the group rate double.

The first part gives 18r%2A35=6
r=6%2F%2818%2A35%29
r=6%2F%283%2A6%2A35%29
r=1%2F%283%2A35%29------the one-man rate.

Using 2 men would give 2r=2%2F%283%2A35%29 as the TWO-man rate.
Question would be how many of two-men build 4 ships in 14 days?
n, how many of two-men,
highlight_green%28n%2A%282%2F%283%2A35%29%29%2A14=4%29

n=4%283%2A35%29%2F%282%2A14%29
n=%284%2A3%2A5%2A7%29%2F%282%2A2%2A7%29
n=15

This should be 2%2A15=highlight%2830%2Amen%29.


The other interpretation from the beginning may be EACH man will work at DOUBLE his typical rate
so the one-man rate could be 2%2F%283%2A35%29, and then n=15 would really be FIFTEEN men.
