Question

It took a machine 4 minutes to fill 100 bottles. How long will it take the machine to fill 350 bottles?

Answer 1

14 minutes

Explanation:

4 x every 100 bottles

100, 200, 300 = 3

4 x 3 = 12

if 4 minutes is for every 100 bottles, then 50 is half of 100. so 4 divided by 2 is 2

12 + 2 = 14
