- 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 Mark took to do History project = 1 h 30 min
Time that Mark took to do Social studies project = 30 min
Total time that Mark spent on both projects
= 1 h 30 min + 30 min
= 2 h
(b)
Time that Mark spent on Science project longer than Social studies project
= 1 h 30 min - 30 min

Answer(s): (a) 2 h; (b) 1 h
