Question

A machine fills 150 bottles of water every 8 minutes. How many minutes does it take this machine to fill 675 bottles?

Answer 1

36 minutes

First find how many bottles can be filled in one minute. So divide 150 by 8.
The machine can fill 18 3/4 or 18.75 bottles in one min.
Now divide 675 by 18.75 = 36 mins to fill 675 bottles
