Ethan spent 3 h 45 min on his Science Project. He spent another 30 min on his Social studies project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Social studies project?
(a)
Time that Ethan took to do Science project = 3 h 45 min
Time that Ethan took to do Social studies project = 30 min
Total time that Ethan spent on both projects
= 3 h 45 min + 30 min
= 4 h 15 min
(b)
Time that Ethan spent on Science project longer than Social studies project
= 3 h 45 min - 30 min
= 3 h 15 min
Answer(s): (a) 4 h 15 min; (b) 3 h 15 min
