Nora:
8 rolls per 10 min = 8/10 roll/min
= 4/5 roll per min

Eli:
10 rolls per 12 min = 10/12 roll/min
= 5/6 roll per min

Eli is faster; 5/6 > 4/5

Hello!

Divide the amount of rolls they can make (10) and (8) by the amount of time they have (40 mins):

40/10 = 4
40/8 = 5

So, Eli will finish making the rolls first.

I hope that was helpful! c:
