Unit Rates — Definition & Examples

Liz, Sandra and Jarel run the school screenprinting club together. They each prepare their screen and start printing. Jarel made $4$ prints in $5$ minutes. Sandra made $15$ prints in $14$ minutes. Liz made $30$ in $15$ minutes. Rank them from the slowest to fastest.

It is worth noting that fastest is not always better in screenprinting. In this case however, it is a contest for speed!
