Answer:
1 minute
Step-by-step explanation:
We can see that Lisa types 165 words in 3 mins.
So she types 55 words in 1 minute.
How did I work that out?
Well, all you really do is [tex]\frac {165}{3}[/tex] which is equal to [tex]\frac{55}{1}[/tex] if you divide top and bottom by 3. Anything divided by 1 is itself.
