Marley has read 112.5 pages of a book. by the end of today, she plans to have read at least a total of 360 pages. if she reads 45 pages per hour, what is the minimum amount of time she should devote to reading today? hours and minutes

She will need 5 and a half hours. First step is to do 360-112.5 the pgs she read and her goal. then you'll get 247.5. To find how many hours you need to find the unit rate. so 247.5 divided by 45 is 5.5 hours. 

hope this helped. can u mark me as the brainiest answer
