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.

✔ 1.5
words/second is the unit rate for Tristan.

✔ 2
words/second is the unit rate for Ebony.
So,
✔ Shanya
is the fastest typist.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
