Answer:
420/89
Step-by-step explanation:
What we know:
Demetrius scored 28 points in 356 seconds.
To get the per second rate divide 28 by 356.
28/356 = 7/89
Here, we're looking for the per minute rate, so multiply the previous rate by 60.
(7*60)/89 = 420/89 (Since this asks for an improper fraction, I'll keep it as so.)
