Answer:
In this question, Maggie's home computer has greater download rate of megabytes in each minute.
Explanation:
Maggie's home computer downloads 7-megabyte program in 5/6 minute
=> In each minute, it can download a program with: 7 / 5 x 6 =8.4 megabytes
Similarity, Brooke's home computer downloads 9-megabyte program in 1 1/4 minute (1 1/4 minute = 5/4 minute)
=> In each minute, it can download a program with: 9/5 x 4 = 7.2 megabytes
As 8.4 > 7.2
So that Maggie's home computer has greater download rate of megabytes in each minute.
