A class is practicing their typing skills. They want to find out who is the most efficient typist.
A 3-column table with 4 rows. Column 1 is labeled Name with entries James, Shanya, Tristan, Ebony. Column 2 is labeled number of words with entries 15, 120, 30, 100. Column 3 is labeled time (seconds) with entries 30, 40, 20, 50.
Find the unit rate for each person’s typing test in words per second.
0.5 words/second is the unit rate for James.
3 words/second is the unit rate for Shanya.
words/second is the unit rate for Tristan.
words/second is the unit rate for Ebony.
So,
is the fastest typist.
