A group of 5 girls went to the library to study for an upcoming biology test. Each girl studied for the amount of time. If the total amount of time they spent studying was 8 hours, how long did each girl study for?
x represents how long each girl studied for
5x = 8 divide 5 on both sides and you get 1.6, so the amount each girl spent studying is 1 hour and 36 minutes
