3 hours = 180 minutes
= 180 minutes / 30 windows
= 6 minutes

This is my work but I am not sure if it is right. Please check over.

3hours=all
all=30windows
3hours=30windows
3hours=3 times 60mins=180mins
180mins=30windows
divide both sides by 30
6mins=1window

true,
you are correct
you could check by doing
number of windows times time per window=6hours
30*6=180
true

yes
