Question

Jason started his project at 2:30 p.m and finished 2 hours and 15 minutes later . He spent 25 minutes doing research, 30 minutes writing a report and the rest of the time building a model. What time did he finish his project? How much time did he spend building the model?

Answer 1

2:30 
2 hrs and 15 minutes later 
= 
4:45 

2:30 
+ 30 
= 
3:30
+ 25
= 3:55

4:45 - 3:55
= 50 minutes

He finished his project at 4:45.
He spent 50 minutes building the model.
