Answer:
Sanjay watched television last weekend for 180 minutes.
Step-by-step explanation:
Sanjay watched 3 television shows and one movie on television last week.
Time duration of 1 television shows = 30 mins
Time duration of 3 television shows = 3* 30 = 90 mins
Time duration of movie = 90 mins
Total number of minutes Sanjay watched television last weekend = Time duration of 3 television shows + Time duration of movie
= 90 + 90
= 180 min
So, Sanjay watched television last weekend for 180 minutes.
