2. While on vacation, Erika's favorite activity is catching some rays while reading novels by the pool.
She can read 40 pages of a book in 50 minutes.

Answer:

144 pages

Step-by-step explanation:

3 hours * 60 = 180 minutes

40 pages / 50 minutes = x pages / 180 minutes

40/50 = x/180

cross multiply

50x = 40 * 180

50x = 7200

x = 7200 ÷ 50

x = 144
