Respuesta :

Answer:

1:42

Step-by-step explanation:

Add the amount of time he watched his sister: 15+5+13=33

Subtract the end time by the amount of time he watched his sister: 2:15-33

-To do this I first I subtracted 15 minutes from the 33 to the 2:15 so you are left with 2:00 and 18 mins

- now subtract 18 mins from 2:00 or 60 = 1:42
