Caroline can sketch 2 cartoon strips in five hours. How long will it take her to sketch 4 strips?

Answer 1

If Caroline can sketch 2 cartoon strips in five hours, then she can sketch 1 cartoon strip in 5/2 = <<5/2=2.5>>2.5 hours.
Therefore, it will take her 4 * 2.5 = <<4*2.5=10>>10 hours to sketch 4 strips. Answer: \boxed{10}.
