Fred spent 3 h 35 min on his Science Project. He spent another 55 min on his History project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his History project?
(a)
Time that Fred took to do Science project = 3 h 35 min
Time that Fred took to do History project = 55 min
Total time that Fred spent on both projects
= 3 h 35 min + 55 min
= 4 h 30 min
(b)
Time that Fred spent on Science project longer than History project
= 3 h 35 min - 55 min
= 2 h 40 min
Answer(s): (a) 4 h 30 min; (b) 2 h 40 min
