Question

Mayerlin read 28 1/2 pages in 2/3 of an hour. At what rate, in pages per hour, did she read?

Answer 1

Answer: 42.75 in page per hours

Explanation:

`28(1)/(2) \ =\ (2)/(3) \\\\x \ = \ 1`

Hence,

`\displaystyle\\x=(28(1)/(2)*1 )/((2)/(3) ) \\\\x=((28*2+1)/(2) )/((2)/(3) ) \\\\x=(3*(56+1))/(2*2) \\\\x=(3*57)/(4) \\x=(171)/(4)\\\\x= 42.75`
