word problem
caroline can sketch 8 cartoon strips in two hours. how long will it take her to sketch 12 strips?
She needs to sketch 12 - 8 = 4 more strips.
4 / 8 = 1/2
She will need 1/2 the time it took to sketch the first 8 strips.
2hrs * 1/2 = 1 hr.
2 hrs + 1 hr = 3 hrs
It will take her 3 hrs to sketch 12 strips.
Because she has already taken 2 hrs to sketch 8 strips, it will take
her one more hour to finish sketching 12 strips.
