Time differences

Problem
Look at the time on the following clocks.

A clock. The short hand points to 12 and the long hand points to the third tick mark after 1.
How much time has passed from the first clock to the second clock?
The time passed is less than
\[1\] hour.
minutes

Answer 1

No time has passed between the first and second clocks as both indicate 11:18. Had the times been 11:18 and 12:03, respectively, the elapsed time would have been 45 minutes.

Step-by-step explanation:

The student's question involves calculating the elapsed time between two different clock readings; specifically, the time difference from one analog clock to another when the hands of the clocks represent different times. According to the description, both clocks show the same time: the short hand points about halfway between 11 and 12, and the long hand points to the third tick mark after 6. This means both clocks indicate that it is 11:18. Since the times are the same, no time has elapsed between the first and second clocks.

If the second depiction of the clocks representing 12:03 had been compared to the first clock indicating 11:18, we would calculate the time difference by determining the time intervals. We know that each tick mark on the clock represents 1 minute, and there are 60 minutes in an hour. Counting the minute intervals from 18 to 60 would give us 42 minutes, and then adding the 3 minutes past the hour gives us a total of 45 minutes elapsed.
