    WK - SEC
    1 - 1
    2 - 2
    3 - 4
    4 - 8
    5 - 16
    6 - 32
    7 - 64
    8 - 128
    9 - 256
    10 - 512
    11 - 1024
    12 - 2048
    13 - 4096
    14 - 8192
    15 - 16384
    16 - 32768
    17 - 65536
    18 - 131072
    19 - 262144
    20 - 524288

    As you can see -- you'd spend 524,288 seconds on homework in week 20. That's over 8,738 minutes or 145.6 hours.

    Continue doubling the seconds until you reach week 36.

    I continued doubling the seconds untill i got to week 36..The week 36 shows me 3.435974e+10..I don't know if it was an error? Sorry, please more help.

    It must be an error. Probably your calculator can't handle this many digits.

    You can type your numbers into the Google search box. It can handle numbers with any number of digits.

    Thank you Ms. Sue,
    I'm greatful for your help here..week 36 finally came down to 34359738368..So how do i get the minutes or the hours answer, just like you did in week 20?? Please show me your work?

    You're welcome.

    Since there are 60 seconds in a minute, and 60 minutes in an hour, divide your number of seconds by 360 to find the number of hours.
