Answer 1

Answer:

(we know 1h=60minutes)

Carol spent for homework in

Mathematics=1h 15minutes=75 minutes

science=1/3h=60/3=20 minutes

filipino=48 minutes

English =42 minutes

total time=75+20+48+42=185minutes

=(60×3)+5 minutes=3h 5 minutes

60 minutes=1h

1minute=1/60 h

5minute=5/60=1/12 h

so answer is 3 1/12 hours
