Answer: 50 seconds

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.
