Tom and some friends went to a movie the show started at 2:30 PM and ended at 4:15 PM how long is the movie last

1 hour and 45 mins

Step-by-step explanation:

As mentioned,

Starting time = 2:30 PM

Ending time = 4:15 PM

The given time is in hours and minutes, to calculate the duration of movie, time should be converted into a same unite minutes.

1 hour = 60 minutes

Therefore,

2:30 = 2 hours and 30 mins = 2*60 + 30 mins = 150 mins

4:15 = 4 hours and 15 mins = 4*60 + 15 mins = 255 mins

The duration = Ending time - Starting time

=> 255 - 150

=> 105 mins

or

60 + 45

1 hour and 45 mins
