- How much longer did he spend on his Science project than his Science project?
(a)
Time that Archie took to do Social studies project = 2 h 45 min
Time that Archie took to do Science project = 40 min
Total time that Archie spent on both projects
= 2 h 45 min + 40 min
= 3 h 25 min
(b)
Time that Archie spent on Science project longer than Science project
= 2 h 45 min - 40 min
= 2 h 5 min
Answer(s): (a) 3 h 25 min; (b) 2 h 5 min
