Answer:
The rate of Krystal is higher
Step-by-step explanation:
Assume that they earned P points in the game
then the rate of Quan = 
and the rate of Krystal = 
∵
(if two fractions have same numerator then the greatest fraction which has the smallest denominator)
∴ The rate of Krystal is higher than the rate of Quan
* To be sure let P = 90 as an example
The rate of Quan = 90/45 = 2 points per minute
The rate of Krystal = 90/30 = 3 points per minute
So the rate of Krystal is higher
