Ivan spent 3 h 55 min on his History Project. He spent another 40 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 Ivan took to do History project = 3 h 55 min
Time that Ivan took to do Chinese project = 40 min
Total time that Ivan spent on both projects
= 3 h 55 min + 40 min
= 4 h 35 min
(b)
Time that Ivan spent on Science project longer than Chinese project
= 3 h 55 min - 40 min
= 3 h 15 min
Answer(s): (a) 4 h 35 min; (b) 3 h 15 min
