Albert spent 2 h 35 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 Albert took to do History project = 2 h 35 min
Time that Albert took to do Mathematics project = 35 min
Total time that Albert spent on both projects
= 2 h 35 min + 35 min
= 3 h 10 min
(b)
Time that Albert spent on Science project longer than Mathematics project
= 2 h 35 min - 35 min
= 2 h
Answer(s): (a) 3 h 10 min; (b) 2 h
