You a building contractor and need to determine how much it will take to complete a task. it usually takes 240 mintues to varnish the window frames on a house

60 minutes are in an hour so 240/6=4 so 4 hours :) Hope this helps. If you have anymore questions let me know

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
