Jim stopped reading at 8:05, after reading for 1 hour and 2 minutes when we started at 6:45.
How do we add time?
In time problems, we need to know the relations between seconds, minutes, hours, and days.
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds.
How do we solve the given question?
We are informed that Jim starts reading at 6:45.
He reads for 1 hour and 20 minutes.
We add this time to the time he starts reading to find the time when Jim stops reading.
First we add hours, 6 + 1 = 7 hours.
Now we add minutes, 45 + 20 = 65 minutes. But we know 60 minutes = 1 hour, so we can say 65 minutes = 1 hour and 5 minutes.
So when we calculate the total time, we get,
Jim stopped reading at 7 + 1:05 = 8:05.
∴ Jim stopped reading at 8:05, after reading for 1 hour and 20 minutes when we started at 6:45.
