- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Social studies project?
(a)
Time that Oscar took to do Chinese project = 3 h 15 min
Time that Oscar took to do Social studies project = 45 min
Total time that Oscar spent on both projects
= 3 h 15 min + 45 min
= 4 h
(b)
Time that Oscar spent on Science project longer than Social studies project
= 3 h 15 min - 45 min
= 2 h 30 min
Answer(s): (a) 4 h; (b) 2 h 30 min
