Eric spent 2 h 40 min on his Chinese Project. He spent another 35 min on his Mathematics project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Mathematics project?
(a)
Time that Eric took to do Chinese project = 2 h 40 min
Time that Eric took to do Mathematics project = 35 min
Total time that Eric spent on both projects
= 2 h 40 min + 35 min
= 3 h 15 min
(b)
Time that Eric spent on Science project longer than Mathematics project
= 2 h 40 min - 35 min
= 2 h 5 min
Answer(s): (a) 3 h 15 min; (b) 2 h 5 min
