Connor and Robert are making posters for Keep America Beautiful Month. Connor worked on his poster from 9:17 a.m. until 10:02 a.m. Robert worked on his poster for 1 hour and 10 minutes. How much longer did Robert work than Connor?.

Answer 1

geez - this at least the 3rd time around on this one
Since there are 60 minutes in an hour, Connor worked
(60-17) + 2 = ____ minutes
Now subtract that from Robert's time

Answer 2

10:02 = 9 am + 62 minutes, call it 9:62 maybe :)
9:62 - 9:17 = 45 minutes for Connor
Robert = 60 min + 10 min = 70 min
Robert - Connor = 70 - 45 = 25 minutes
