Sean reads his book by what speed This answer is quite unorthodox LIke a speed question. We will find the amount of pages Sean read per hour or minutes if u want to convert
So speed of reading = amount of pages read/ time = 144/3 hours or 144/3*60 minutes =48 or 8/10 minutes
So time taken to complete his book at the same pace he is reading amount of pages to read/speed of reading =264/48 or 264*10/8 =5.5 hours or 330 minutes
