The following table shows how many multiplication problems 44 students were able to solve in different amounts of time. for example, murray solved 5858 problems in 22 minutes. student problems minutes murray 5858 22 kris 7878 33 logan 8484 33 taylor 9292 44 which student solved problems at a rate of 2828 per minute?

Logan

Step-by-step explanation:

Here the given table,

Student :       Murray             Kris            Logan          Taylor

Problem :        58                  78                84               92

Time(min) :       2                   3                    3                 4        

Thus,

The rate of Murray per minute =  

The rate of Kris per minute =  

The rate of Logan per minute =  

The rate of Taylor per minute =  

Therefore, Only Logan can solve the problem at the rate of 28 per minutes.
