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