350 slices of pizza are eaten per second in the United States. How many are eaten per hour? (Hint there are 3,600 seconds per hour) Please explain to me how to do this.
1hour=60mins 1min=60seconds so 1hr=60*60seconds=3600seconds
ratio and proportion
[tex]\frac{350pieces}{1second}=\frac{xpieces}{3600seconds}[/tex] times both sides by 3600 seconds [tex]\frac{1260000pieces}{1}=xpieces[/tex] the answer is 1260000 pieces
