Question

If i read 60 pages in 1 5/12 hours how long will it take me to read 120 pages

Answer 1

Explanation:

Direct proportion

60: 1 5 /12 = 120 : x

60: 17/12 = 120:x

Product of extremes = product of mean

60*x = (17/2)*120

`60*x=(17)/(12)*120\\\\60*x=17*10\\\\x=(17*10)/(60)\\\\x=(17)/(6)\\\\x=2(5)/(6)`

It will take 2 5/6 hours to read 120 pages
