On monday, tuesday, and wednesday, stephen practiced the piano from 4: 15 p. m. until 5: 45 p. m. in total, how long did he practice during those three days?

From 4:15 to 5:45 is a difference of 1:30 or an hour and 30 mins

1:30 x 30 = 3hours + 30mins + 30 mins + 30 mins

               =  "4:30" or "four hours and 30 mins" or "four and a half hours"

PLEASE GIVE BRAINIEST ANSWER

From 4:15 to 5:45 is 90 mins, or 1 hour and 30 mins. if you add 1 hour, 30 mins + 1 hour, 30 mins + 1 hour, 30 mins you will get 3 hours, 90 mins. this becomes 4 hours and 30 mins.
