Jayden has been reading a 275-page book for 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 50min, to finish the book (reading and skimming combined), how many pages did jayden have to skim through?

Because he read 10 pages in 15 minutes, and 15 pages in 10 minutes, Jayden read a total of 25 pages. If we subtract 275 from 25, we get 250. In conclusion, Jayden had to skim through 250 pages in 5 hours and 50 minutes.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

$12. that is my answer.
