Answer:Option B. 5 hours.Step-by-step explanation:Steve reads 80 pages in 2 hours and 40 minutes.1 hour = 60 minutes2 hour 40 minutes = (2 × 60) + 40 = 160 minutesSpeed of reading of Steve = [tex]\frac{80}{160}[/tex]                                              = 0.5 page per minuteCassandra reads twice as fast as Steve.Therefore, speed of reading of Cassandra = 0.5 × 2                                                                        = 1 page per minuteTherefore, time to read 300 pages by Cassandra = 300 × 1                                                                                    = 300 minutesNow convert minutes to hours[tex]\frac{300}{60}[/tex]= 5 hoursCassandra will take 5 hours to read 300 page book.
