- 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 Eric took to do Science project = 1 h 30 min
Time that Eric took to do Social studies project = 50 min
Total time that Eric spent on both projects
= 1 h 30 min + 50 min
= 2 h 20 min
(b)
Time that Eric spent on Science project longer than Social studies project
= 1 h 30 min - 50 min
= 40 min
Answer(s): (a) 2 h 20 min; (b) 40 min
