Question

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.

Answer 1

350pieces/second


1hour=60mins
1min=60seconds
so 1hr=60*60seconds=3600seconds

ratio and proportion

$\frac{350pieces}{1second}=\frac{xpieces}{3600seconds}$
times both sides by 3600 seconds
$\frac{1260000pieces}{1}=xpieces$
the answer is 1260000 pieces

to do that, multiply 350 by 3600

Answer 2

You multiply 350 by 3600 and then you get the answer.
