Based on a 2008 study, children 6–11 years old spend 45 minutes each day watching television. How many hours do these children watch television in 2 weeks if they are allowed to watch television 4 days a week?
The children watch a total of 45 x 4 = 
<gadget id="calculator">45*4</gadget>
<output>180</output>
180 minutes in a week.
In hours, this is equal to 180/60 = 
<gadget id="calculator">180/60</gadget>
<output>3</output>
3 hours a week.
Thus, these children watch 3 x 2 = 
<gadget id="calculator">3*2</gadget>
<output>6</output>
6 hours in two weeks.
