6. On his homework, Maria complete 6 problems in 13 minutes.

$

a. Write a unit rate for this situation at problems per minute.

The correct unit rate would be 13 minutes/6 problems (written like a fraction)

or it could be 1 problem/2.17 minutes

Step-by-step explanation:

Unit rates are just a time frame over a measurable occurrence, like math problems or distances. The most common example of a unit rate would be speed limits, like 15 miles/1 hour. So to make a unit rate out of the word problem you simply write out the numbers and units like a fraction, and simplify it if necessary.
