Albert spent 2 h 45 min on his Mathematics Project. He spent another 45 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 Albert took to do Mathematics project = 2 h 45 min
Time that Albert took to do History project = 45 min
Total time that Albert spent on both projects
= 2 h 45 min + 45 min
= 3 h 30 min
(b)
Time that Albert spent on Science project longer than History project
= 2 h 45 min - 45 min
= 2 h
Answer(s): (a) 3 h 30 min; (b) 2 h
