Jayden has been reading a 275-page book for an English class. On average, he has read about 10 pages in 15 minutes. With a deadline looming, Jayden realizes that he won't finish in time unless he skims through the rest of the book. If he skims the book, he can cover 15 pages in 10 minutes. If it takes Jayden 5 hours and 50 minutes to finish the book (reading and skimming combined), how many pages did Jayden have to skim through?

Total=275
R1=10p per 15 mins
R2=15p per 10 mins
T=5 hrs 50 mins
Let x pages be read
Pages skimmed=275-x
T1=x/(10/15)
T2=(275-x)/(15/10)
T1+T2=60*5+50=350 mins
x/(10/15)+(275-x)/(15/10)=350
Just solve
x=200
Pages skimmed=275-200=75
Hope you understood :)
