Luke spent 3 h 55 min on his History Project. He spent another 45 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 Luke took to do History project = 3 h 55 min
Time that Luke took to do Chinese project = 45 min
Total time that Luke spent on both projects
= 3 h 55 min + 45 min
= 4 h 40 min
(b)
Time that Luke spent on Science project longer than Chinese project
= 3 h 55 min - 45 min
= 3 h 10 min
Answer(s): (a) 4 h 40 min; (b) 3 h 10 min
