Let x=number of minutes it would take the machine to produce 238 bolts
We know that this machine produces bolts at the rate of 389/34 bolts per min and we have specified that in x minutes it will produce 238 bolts. In other words, the rate at which the machine produces bolts (bolts/min) times x minutes has to equal 238 bolts.
So, our equation to solve is:
(389/34)*x=238 multiply each side by 34
389x=8092 divide each side by 389
x=20.8 minutes------ans
