Steve reads 80 pages in 2 hours and 40 minutes. if cassandra reads twice as fast as steve, how long will it take her to read a 300 page book? o a 4 hours 40 minutes o b. 5 hours c.5 hours 20 minutes o d. 5 hours 40 minutes

Option B. 5 hours.

Step-by-step explanation:

Steve reads 80 pages in 2 hours and 40 minutes.

1 hour = 60 minutes

2 hour 40 minutes = (2 × 60) + 40 = 160 minutes

Speed of reading of Steve =

                                             = 0.5 page per minute

Cassandra reads twice as fast as Steve.

Therefore, speed of reading of Cassandra = 0.5 × 2

                                                                       = 1 page per minute

Therefore, time to read 300 pages by Cassandra = 300 × 1

                                                                                   = 300 minutes

Now convert minutes to hours

= 5 hours

Cassandra will take 5 hours to read 300 page book.

The correct answer is b. 14(m-8).

This is because it says that the weight of the boxes drew lifted were 8 pounds less than what marco lifted.  This can be represented by m-8.  You then need to multiply this by the amount of boxes that drew lifted, or 14.
