Adam is playing a new memory game on the computer. He graphed the points he earned below.
What is his rate of points per minute?
A.
200 points per minute
B.
250 points per minute
C.
50 points per minute
D.
100 points per minute
To find Adam's rate of points per minute, we need to divide the total points earned by the total time in minutes.
From the graph, Adam earned a total of 500 points in 5 minutes.
So, 500 points / 5 minutes = 100 points per minute.
Therefore, Adam's rate of points per minute is 100 points per minute, which is option D.
