Japheth spent 1 h 15 min on his Mathematics Project. He spent another 30 min on his Chinese project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Chinese project?
(a)
Time that Japheth took to do Mathematics project = 1 h 15 min
Time that Japheth took to do Chinese project = 30 min
Total time that Japheth spent on both projects
= 1 h 15 min + 30 min
= 1 h 45 min
(b)
Time that Japheth spent on Science project longer than Chinese project
= 1 h 15 min - 30 min
= 45 min
Answer(s): (a) 1 h 45 min; (b) 45 min
