Luis spent 1 h 30 min on his History Project. He spent another 35 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 Luis took to do History project = 1 h 30 min
Time that Luis took to do Mathematics project = 35 min
Total time that Luis spent on both projects
= 1 h 30 min + 35 min
= 2 h 5 min
(b)
Time that Luis spent on Science project longer than Mathematics project
= 1 h 30 min - 35 min
= 55 min
Answer(s): (a) 2 h 5 min; (b) 55 min
