Ivan spent 1 h 40 min on his Science 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 Ivan took to do Science project = 1 h 40 min
Time that Ivan took to do History project = 40 min
Total time that Ivan spent on both projects
= 1 h 40 min + 40 min
= 2 h 20 min
(b)
Time that Ivan spent on Science project longer than History project
= 1 h 40 min - 40 min
