Elyse read 4 books in 3 h. She took the same amount of time to read each of the first 3 books. She took 48 min longer to read the fourth book than each of the first 3 books. She finished reading all the books at 16 14. What time did she start reading the fourth book?
Duration that Elyse took to read the first book = 1 u
Duration that Elyse took to read the second book = 1 u
Duration that Elyse took to read the third book = 1 u
Duration that Elyse took to read the fourth book = 1 u + 48 min

Total duration that Elyse took to read the four books 
= 1 u + 1 u + 1 u + 1 u + 48 min
= 4 u + 48 min

4 u + 48 min = 3 h
4 u = 180 min - 48 min
4 u = 132 min  

1 u = 132 min ÷ 4 = 33 min

Duration that Elyse took to read the fourth book
= 33 min + 48 min
= 81 min
= 1 h 21 min

1 h 21 min before 16 14: 14 53

Time that Elyse started to read the fourth book = 14 53

Answer(s): 14 53
