    Answer: 50 seconds

    Step-by-step explanation:

    We need to convert 5hours to seconds.

    5hours = 5 * 60*60 = 18000sec.

    $90 = 18000 sec

    $0.25 = x

    x = 18000 * 0.25 / 90

    x = 4500/90

    x = 50

    Therefore it takes 50 seconds to earn $0.25

    First find her rate per hour by dividing $90 by 5 hours:

    90 / 5 = 18

    She makes $18 in one hour.

    1 hour = 3600 seconds.

    Divide her hourly rate by 3600 to find how much she makes per second:

    18 / 3600 = $0.005 per second.

    Now divide $0.25 by 0.005 to find the number of seconds needed:

    0.25 / 0.005 = 50

    It takes 50 seconds.
