Alex reads 12 pages in 10 min. jenna reads 15 pages in 12 min. they are both reading a 60 page magazine. who will finish reading the magazine first?

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
