Eric spent 3 h 20 min on his Social studies Project. He spent another 55 min on his Chinese project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Chinese project?
(a)
Time that Eric took to do Social studies project = 3 h 20 min
Time that Eric took to do Chinese project = 55 min
Total time that Eric spent on both projects
= 3 h 20 min + 55 min
= 4 h 15 min
(b)
Time that Eric spent on Science project longer than Chinese project
= 3 h 20 min - 55 min
= 2 h 25 min
Answer(s): (a) 4 h 15 min; (b) 2 h 25 min
