mason played piano for one hour on monday. on tuesday, he played for 30 minutes longer. On wednesday, he played for 15 minutes longer than tuesday. how long did he play piano on wednesday?

If he played for 30 mins on Tuesday and played for 15 mins longer on Weds then he did on Tues, you add 30+15 to get 45.
So on Weds he played for 45 mins. 
It would be 1hr and 45 mins of playing on Weds because on Monday Mason starts playing for one hour and then add the 45 mins. Right?

Monday 1hr
Tue 1hr 30 min
Wed 1hr 45min
