Johns goes to the gym 3 times a week.  He spends 1 hour each day lifting weight. Additionally, he also spends a third of his weightlifting time warming up and doing cardio each day.  How many hours does he spend at the gym a week?
He spends 60/3=<<60/3=20>>20 minutes warming up
So he spends 60+20=<<60+20=80>>80 minutes at the gym per day
That means he spends 80*3=<<80*3=240>>240 minutes at the gym
So he spends 240/60=<<240/60=4>>4 hours at the gym a week
