A bottling machine can fill 210 bottles every 5 minutes how many bottles can it fill in 1 hour

Answer 1

2520 bottles in an hour

12 x 210 = 2520

5 minutes is 1/12 of an hour

210/1/12 = B/1, set ratios of bottles to time equal, but make sure you have the same units, either hours or minutes

In minutes the ratio would be 210/5 = B/60, cross multiply and solve for B
