Answer:
50 seconds
Step-by-step explanation:
Given: Clare is paid $90 for 5 hours of work.
To find: how many seconds does it take for her to earn 25 cent?
Solution: It is given that Clare is paid $90 for 5 hours of work.
We know that $1 is equal to 100 cents.
1 hour is equal to 3600 seconds
So, we get $[tex]90=90\times100=9000[/tex] cents
5 hours[tex]=5\times3600=18000[/tex] seconds
Therefore, time taken to earn 1 cent[tex]=\frac{18000}{9000} =2[/tex] seconds
So, time taken to earn
25 cents[tex]=25\times2[/tex]
[tex]=50[/tex] seconds
Hence, it take 50 seconds to earn 25 cents.
