90 · One hour plus half an hour is 60 + 30 = 90 minutes.
45 minutes · From 10:15 to 11:00 is 45 minutes.
15 minutes · From 10:00 to 10:15 is 15 minutes. Count by fives: 5, 10, 15.
True · From 2:00 to 2:30, thirty minutes pass. Count by tens: 10, 20, 30.
15 · 10:45 minus 10:30 is 15 minutes.
45 minutes · From 4:15 to 4:45 is 30 minutes, then 4:45 to 5:00 is 15 more. That is 45 minutes.
45 minutes · From 9:00 to 9:45 is 45 minutes.
False · Jay is wrong. From 4:00 to 5:00 is exactly 1 hour.
1 hour 35 minutes · From 10:45 to 11:45 is 1 hour. Then 11:45 to 12:20 is 35 more minutes, so the movie is 1 hour 35 minutes.
55 · 50 minutes to 9:00 plus 5 more makes 55 minutes.
