Karen can read 10 pages and complete 15 math problems in 30 minutes. How long will it take her to do her homework if she has 30 pages to read and 45 math problems to complete? Your answer should refer to the amount of time in minutes.(1 poi
If Karen can read 10 pages and complete 15 math problems in 30 minutes, then we can find her reading rate and math rate per minute.
Reading rate: 10 pages / 30 minutes = 1/3 pages per minute
Math rate: 15 problems / 30 minutes = 1/2 problems per minute
To find the time it takes for Karen to do her homework, we can use the rates we just found.
Time to read 30 pages = 30 pages / (1/3 pages per minute) = <<30/(1/3)=90>>90 minutes
Time to complete 45 math problems = 45 problems / (1/2 problems per minute) = <<45/(1/2)=90>>90 minutes
Therefore, it will take Karen 90 minutes to do her homework.
