A Person,resting in a boat, notices that 16 waves pass the boat every 38 seconds ... HOw many waves would pass the boat in 55 seconds?

A boy does 0 homework problems in 16 minutes. How many homework problems will he complete in 1 week? :-)

in order to answer that you need to find howmany waves in a second (16/38) which equals to *.42* meanning there will be .42 waves passing every second. then you just multiply it by 55 (.42*55) which equals to 23.2 (23.15789473684.........

hmmm the boy does 0 homework in one week, because 7 days in one week and 24 hours in one day so: 24*7=168, then 60 minutes in an hour, 60*168=10080, and he does 0 in 16 minutes so, 10080/16=630, then 630*0=0, thats it. :smile:

Yeah, but what if his rate grows exponentially? :wink:

well that was not part of the problem, it says he does 0 homework in 16 min, so I deduce that he does 0 in 16 min. So it cannot increase exponentially if 0=0. :biggrin:

16 waves x waves
----------- = ---------------
38 seconds 55 seconds


solve this

you should get
23.16 waves
