A factory can assemble 3,400 Ipods in an 8-hour shift. If the factory were to work around the clock, how long would it take them to assemble 100,000 Ipods?

Answer 1

If a factory can assemble 3400 ipods in an 8 hour shift, it will take the factory x hours to assemble 100,000ipods where x is the time taken by the factory to assemble 100000ipods.

Answer 2

ipods/hour = 3400/8 = number of hours = 425 ipods/hour
425 ipods / hour * h hours = 100,000
h = 100,000/425 = 235.3 hours which is 235.3 / 24 = 9.8 or about ten days

Answer 3

or, as a proportion,
x/100000 = 8/ 3400
if they only work one 8-hour shift per day, then it will take 3 times as long, or 29.4 days
