Julian spent 3 h 15 min on his Social studies Project. He spent another 30 min on his Mathematics project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Mathematics project?
(a)
Time that Julian took to do Social studies project = 3 h 15 min
Time that Julian took to do Mathematics project = 30 min
Total time that Julian spent on both projects
= 3 h 15 min + 30 min
= 3 h 45 min
(b)
Time that Julian spent on Science project longer than Mathematics project
= 3 h 15 min - 30 min
= 2 h 45 min
Answer(s): (a) 3 h 45 min; (b) 2 h 45 min
