John spent 3 h 20 min on his Social studies 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 John took to do Social studies project = 3 h 20 min
Time that John took to do Mathematics project = 50 min
Total time that John spent on both projects
= 3 h 20 min + 50 min
= 4 h 10 min
(b)
Time that John spent on Science project longer than Mathematics project
= 3 h 20 min - 50 min
= 2 h 30 min
Answer(s): (a) 4 h 10 min; (b) 2 h 30 min
