Charlie spent 1 h 50 min on his Mathematics Project. He spent another 50 min on his History project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his History project?
(a)
Time that Charlie took to do Mathematics project = 1 h 50 min
Time that Charlie took to do History project = 50 min
Total time that Charlie spent on both projects
= 1 h 50 min + 50 min
= 2 h 40 min
(b)
Time that Charlie spent on Science project longer than History project
= 1 h 50 min - 50 min
= 1 h
Answer(s): (a) 2 h 40 min; (b) 1 h
