Answer:
Logan solved problems at a rate of 28 problems per minute.
Step-by-step explanation:
To find the number of problems per minute that a person solved, you will divide the number of problems that they solved by the number of minutes that they took.
Murray:
58 problems in 2 minutes,
58 / 2 = 29
He solved problems at a rate of 29 problems per minute.
Kris:
78 problems in 3 minutes,
78 / 3 = 26
He solved problems at a rate of 26 problems per minute.
Logan:
84 problems in 3 minutes,
84 / 3 = 28
He solved problems at a rate of 28 problems per minute.
Since you found that Logan solved problems at a rate of 28 problems per minute, Logan is the student that solved problems at a rate of 28 per minute.
