Question:

How long would it take to make 1,000,000 paper cranes if making one takes 7 min & 11 sec?

Please write in days, hours, weeks, etc.I need math help!!!!

Answer:

If it takes 7*60 + 11 = 431 seconds to make 1 crane, then making one million would take 431,000,000 seconds. There are 3600s*24hr*365.25d = 31,557,600 seconds in an average year. Dividing 431 million by this gives a little over 13 years, with a remainder of 20,751,200 seconds. There are 3600*24*30 = 2,592,000 seconds in an average month. So that gives 8 months with a remainder of 15,200 seconds. There are 3600 seconds in an hour, so that gives 4 hours plus 800 seconds. The 800 seconds = 60*13 + 20 = 13 minutes, 20 seconds. This works out to 13 years, 8 months, 4 hours, 13 minutes, and 20 seconds. Though answers can vary depending on how many days you define to be in a year, and how many days in a month.
7*60 / 60 + 11/60 = 420+11 / 60 = 431/60 seconds to make 1. 431/60 * 1,000,000 = 431,000,000 / 60 = 43,100,000/6 = 21550000/3 seconds. 21550000/3 / 60 = 21550000/180 = 2155000/18 = 1077500/9 minutes 1077500/9 / 60 = 1077500/540 = 107750/54 = 53875/27 hours 53875/27 / 24 = 53875/648 = 83.14040987654320987654320... days. 0.1404098765432098765432...*24 = 3.37037037037037... hours. .37037037037037037... *60 = 22.22222222222... minutes 0.2222222222222*60 = 13.333333333333333 seconds. 83 days, 3 hours, 22 minutes and 13 1/3 seconds.
it takes 431000000 seconds
13 years 8 months 2 hours 13 minutes 20 seconds
