The student that did more maths problems per minute is Diedra.
In order to determine which student did more maths problems per minute, the rate of each student has to be determined. Rate is the total questions solved divided by the time.
Rate = total questions / total time
Malcolm = 15 / 18 = 0.833 problems per minute
Diedra = 16/ 17 = 0.941 problems per minute

Percent change = (new number - old number)/(old number) * 100
new number = 150 (in July)
old number = 120 (in June)
percent change = (150 - 120)/120 * 100
percent change = 30/120 * 100
percent change = 0.25 * 100
