We have a problem about calculating the duration of a movie. The movie starts at 3:10 PM and ends at 4:25 PM. We need to find out how many minutes long the movie is. Let's visualize this with a clock face showing both the start and end times.
Let's understand how to read these times. The format is hours, colon, minutes, followed by AM or PM. 3:10 PM means 3 hours and 10 minutes in the afternoon. 4:25 PM means 4 hours and 25 minutes in the afternoon. The colon separates the hours from the minutes. In 3:10, 3 represents the hours and 10 represents the minutes.
Now let's visualize the problem using a timeline. We'll place the start time 3:10 PM at position zero. The next hour mark is 4:00 PM, which is 50 minutes after 3:10 PM. The end time is 4:25 PM, which is 25 minutes after 4:00 PM. So we can break the problem into two segments: from 3:10 PM to 4:00 PM is 50 minutes, and from 4:00 PM to 4:25 PM is 25 minutes.
Let's calculate the elapsed time step by step. First, from 3:10 PM to 4:00 PM. Since there are 60 minutes in an hour, and we start at 10 minutes past the hour, we have 60 minus 10 equals 50 minutes. Second, from 4:00 PM to 4:25 PM, that's simply 25 minutes. Adding these together, 50 plus 25 equals 75 minutes. So the movie is 75 minutes long.
Let's look at an alternative method. We can convert both times to total minutes from noon. For 3:10 PM, that's 3 hours times 60 minutes plus 10 minutes, which equals 180 plus 10 equals 190 minutes from noon. For 4:25 PM, that's 4 hours times 60 minutes plus 25 minutes, which equals 240 plus 25 equals 265 minutes from noon. Then we subtract: 265 minus 190 equals 75 minutes. This confirms our previous result.
Let's verify our answer and express it in hours and minutes. We found that the movie is 75 minutes long. To convert this to hours and minutes, we divide 75 by 60. That gives us 1 with a remainder of 15. So 75 minutes equals 1 hour and 15 minutes. This makes sense because 1 hour is 60 minutes, plus 15 minutes gives us our total of 75 minutes. Both methods we used gave us the same answer, confirming that our calculation is correct.
