Justin spent 2 h 30 min on his Chinese Project. He spent another 55 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 Justin took to do Chinese project = 2 h 30 min
Time that Justin took to do Mathematics project = 55 min
Total time that Justin spent on both projects
= 2 h 30 min + 55 min
= 3 h 25 min
(b)
Time that Justin spent on Science project longer than Mathematics project
= 2 h 30 min - 55 min
= 1 h 35 min
Answer(s): (a) 3 h 25 min; (b) 1 h 35 min
