Answer:
1000 times greater
Step-by-step explanation:
9.6 * 10^-2 / 9.6 * 10^-5
= (9.6 / 9.6) * (10^-2 / 10^-5)
= 1 * 10^(-2 -( -5))
= 10^3
= 1000
The important information's already given in the question can be used to find the correct answer.

= 9 * h hours
= 9h hours
So we have found from the above discussion that Sarah wrote the correct answer and it was 9h.
