Charlie spent 2 h 35 min on his Mathematics Project. He spent another 50 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 Charlie took to do Mathematics project = 2 h 35 min
Time that Charlie took to do Social studies project = 50 min
Total time that Charlie spent on both projects
= 2 h 35 min + 50 min
= 3 h 25 min
(b)
Time that Charlie spent on Science project longer than Social studies project
= 2 h 35 min - 50 min
= 1 h 45 min
Answer(s): (a) 3 h 25 min; (b) 1 h 45 min
