Zane spent 1 h 50 min on his Mathematics Project. He spent another 40 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 Zane took to do Mathematics project = 1 h 50 min
Time that Zane took to do History project = 40 min
Total time that Zane spent on both projects
= 1 h 50 min + 40 min
= 2 h 30 min
(b)
Time that Zane spent on Science project longer than History project
= 1 h 50 min - 40 min
= 1 h 10 min
Answer(s): (a) 2 h 30 min; (b) 1 h 10 min
