# Three ships

There are three ships moored in the port, which sail together. The first ship returns after two weeks, the second after four weeks, and the third after eight weeks. In how many weeks the ships will meet in the port for the first time? How many times have vessels appeared in the port in the meantime? (do not count the last meeting)

Correct result:

t =  8
a =  3
b =  1
c =  0

#### Solution:

$a=t\mathrm{/}2-1=8\mathrm{/}2-1=3$
$b=t\mathrm{/}4-1=8\mathrm{/}4-1=1$
$c=t\mathrm{/}8-1=8\mathrm{/}8-1=0$
