To work out how long each student will take:
Alex:
60 pages / 12 pages = 5 lots of 12 pages
5 lots multiplied by 10 mins = 50 mins
It will take Alex 50 minutes to finish the book
Jenna:
60 pages / 15 pages = 4 lots of 15 pages
4 lots multiplied by 12 mins = 48 mins
It will take Jenna 48 minutes to finish the book
Therefor Jenna will finish the book first
