Answer:

Sister's books took 920 s more to cover with brown paper than it took pinki's books to cover

Explanation:

Time taken by Pinki's books : 55 min 20s

                                                  = (55x60)+20 s

                                                  = 3320 s

Time taken by sister's books : 1 hr 10 min 40 s

                                                 = (1x60x60) + (10x60) + 40

                                                 = 3600 + 600 + 40

                                                 = 4240 s

As we can see her sister's books took longer time than pinki's books

4240 - 3320 = 920 s

Sister's books took 920 s more than pinki's book
