Xavier spent 3 h 20 min on his History Project. He spent another 40 min on his Science project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Science project?
(a)
Time that Xavier took to do History project = 3 h 20 min
Time that Xavier took to do Science project = 40 min
Total time that Xavier spent on both projects
= 3 h 20 min + 40 min
= 4 h
(b)
Time that Xavier spent on Science project longer than Science project
= 3 h 20 min - 40 min
= 2 h 40 min
Answer(s): (a) 4 h; (b) 2 h 40 min
