Jack spent 1 h 20 min on his Social studies Project. He spent another 35 min on his Chinese project.
- How much time did he spend on both projects?
- How much longer did he spend on his Science project than his Chinese project?
(a)
Time that Jack took to do Social studies project = 1 h 20 min
Time that Jack took to do Chinese project = 35 min
Total time that Jack spent on both projects
= 1 h 20 min + 35 min
= 1 h 55 min
(b)
Time that Jack spent on Science project longer than Chinese project
= 1 h 20 min - 35 min
= 45 min
Answer(s): (a) 1 h 55 min; (b) 45 min
