Janet can sew 35 scarves in 2 hours. At this rate, how many scarves can she sew in 5 hours? How long will it take to sew one scarf?

Question

This is really confusing me. It is a question for an A-CAASPP Prep question.

Answer 1

s represents the number of scarves

35 : 2 :: s : 5   proportion

2s = (5)(35)     product means/extremes

 

Can you solve for s?

 

One scarf in 2 hours / 35, or 120 min / 35, 3.428571429 minutes

 

I doubt that a prep course has problems that result in such a number. Check your data.
