Answer:

1 hour 58 minutes, or 118 minutes

Explanation:

You want to know how long a movie lasted if it started at 3:12 pm and ended at 5:10 pm.

Arithmetic

The time the movie lasted is found by subtracting the start time from the end time.

(5 h, 10 min) -(3 h, 12 min) = (5 -3) h, (10 -12) min = 2 h, -2 min

The movie lasted 2 minutes less than 2 hours. There are 60 minutes in an hour, so 2 minutes less than 2 hours is 1 hour, 58 minutes.

The movie lasted 1 hour, 58 minutes.

Additional comment

Time in hours, minutes, seconds is a base-60 counting system the same way that angles in degrees, minutes, seconds are. Many calculators provide math functions for angles that can be used for time as well.

The attachment shows the difference between 5:10 and 3:12 when written as degrees and minutes in place of hours and minutes. The 1°58' is equivalent to the duration 1 hour 58 minutes.
