Rael spent 2 h 55 min on his Chinese Project. He spent another 45 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 Rael took to do Chinese project = 2 h 55 min
Time that Rael took to do Mathematics project = 45 min
Total time that Rael spent on both projects
= 2 h 55 min + 45 min
= 3 h 40 min
(b)
Time that Rael spent on Science project longer than Mathematics project
= 2 h 55 min - 45 min
= 2 h 10 min
Answer(s): (a) 3 h 40 min; (b) 2 h 10 min
