Bobby spent 3 h 15 min on his Chinese Project. He spent another 50 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 Bobby took to do Chinese project = 3 h 15 min
Time that Bobby took to do Mathematics project = 50 min
Total time that Bobby spent on both projects
= 3 h 15 min + 50 min
= 4 h 5 min
(b)
Time that Bobby spent on Science project longer than Mathematics project
= 3 h 15 min - 50 min
= 2 h 25 min
Answer(s): (a) 4 h 5 min; (b) 2 h 25 min
