Answer:
It will take 2 and a half hours
Step-by-step explanation:
Well 40 can go into 200 5 times so you would do 5 times 30 minutes which would be 150 minutes and then you would divide it by 60 to simplify which would be 2 hours and 30 minutes. So it will take 2 and a half hours to make 200 harmonicas.
200/40 = 5
5 * 30 = 150
150/60 = 2 hours and 30 minutes
