machine a produces 100 parts thrice as fast as machine b does. machine b produces 100 parts in 30 minutes. if each machine produces parts at a constant rate, how many parts does machine a produce in 6 minutes?
multiply(multiply(divide(100, 30), const_3), 6)
machine b produces 100 part in 30 minutes . machine a produces 100 parts thrice as fast as b , so machine a produces 100 parts in 30 / 3 = 10 minutes . now , machine a produces 100 parts in 10 minutes which is 100 / 10 = 10 parts / minute . 10 parts x a total of 6 minutes = 60 d
