Mr. Ailey gave his class 45 minutes to read. Davida reads 27 3/4 pages in that time. At what rate, in pages per hour, did Davida read? A 42
B 36
C 34
D 37

37 pages per hour

Step-by-step explanation:

Given that :

Time Given to read = 45 minutes ; 45 / 60 = 0.75

Number of pages readable ad by Davida within the given time frame = 27 3/4 pages

David's reading rate in pages per hour :

Number of pages read / time taken (hrs)

[27 3/4] ÷ (45/60)

[111 / 4] ÷ (45/60)

(111 / 4 ) * (60/45)

(111 * 60) / (4 * 45)

6660 / 180

= 37 pages per hour

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
