The number (b) of bolts a machine can make varies directly as the time (t) it operates. it can make 6,000 bolts in 2 hours. how many can it make in 5 hours?
For this case we have a function of the form: b = k * t Where, k: proportionality constant. For this case: k = 6000/2 k = 3000 Substituting values: b = 3000 * t For t = 5 we have: b = 3000 * 5 b = 15000 Answer: it can make in 15000 bolts in 5 hours
