Sam spent 3 h 50 min on his Social studies Project. He spent another 40 min on his Science project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Science project?
(a)
Time that Sam took to do Social studies project = 3 h 50 min
Time that Sam took to do Science project = 40 min
Total time that Sam spent on both projects
= 3 h 50 min + 40 min
= 4 h 30 min
(b)
Time that Sam spent on Science project longer than Science project
= 3 h 50 min - 40 min
= 3 h 10 min
Answer(s): (a) 4 h 30 min; (b) 3 h 10 min
