Melissa works on a poultry farm. She drives to town twice each month to buy supplies. If it takes her 3 hours to drive to town and back, how many hours does Melissa spend driving in a year?
Melissa spends 2x3=<<2*3=6>>6 hours driving each month.
Since there are 12 months in a year, she spends 6x12=<<6*12=72>>72 hours driving each year.
