Question

A frame shop owner is working with her apprentice, who takes four times as long as

she does to frame a poster. Together they can frame 40 posters in an eight-hour
day.

How long does it take the apprentice to frame one poster?

1. 1 hour
2. 8/25 hour
3. 1/4 hour
4. 4 hours

Answer 1

1 hour

Explanation:

25min=1 poster for the shop owner

25×4=100

100×8=800

800÷25=32 posters in 8hrs for the shop owner

1hr×8=8 posters for the apprentice

thus 40 in total
