A machine labels 150 bottles in 20 min. How many min does it take to label 60 bottles?

Answer 1

This can be set up as a proportion. Let x be unknown number of minutes

150 bottles/20 mins = 60 bottles/x mins

Cross multiply: 150(x)=60(20)

Simplify: 150x=1200

Divide both sides by 150: 150x/150=1200/150

x=8 mins
