Caleb types 100 words in 5 minutes. What is the unit rate?
We could work out the unit rate in 2 ways:
Per Minute or Per second.
First we will start of with per minute:
Find out how many seconds are in a minute (60) and multiply by the total minutes, getting the amount of seconds.

Since Caleb trypes 100 words in 5 mins we can say that:
Hence we can try and find
Going further we know:
So we can say:
To get 60 seconds, we divide each side by 60:
