Final answer:
Logan read at a rate of approximately 48 pages per hour, calculated by dividing the total number of pages (66) by the time in hours (1.375).
Step-by-step explanation:
Logan read 66 pages in 1 3/8 hours. To find the rate of pages per hour at which he read, we first need to convert the time from hours and fractions to just hours. Since 3/8 of an hour is 0.375 hours, 1 3/8 hours is the same as 1.375 hours. Next, we divide the number of pages Logan read by the total hours.
Rate = Total Pages / Total Hours = 66 pages / 1.375 hours
Performing the division, we get approximately 48 pages per hour.
