Fred spent 3 h 45 min on his Social studies Project. He spent another 40 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 Fred took to do Social studies project = 3 h 45 min
Time that Fred took to do Mathematics project = 40 min
Total time that Fred spent on both projects
= 3 h 45 min + 40 min
= 4 h 25 min
(b)
Time that Fred spent on Science project longer than Mathematics project
= 3 h 45 min - 40 min
= 3 h 5 min
Answer(s): (a) 4 h 25 min; (b) 3 h 5 min
