Ask the student a question, and give any hints about how they should answer this part.

You are due to attend a meeting at {meetingtime}. As you enter the building you notice the clock below (note that it is morning afternoon)

{clock}

By how many hours and minutes are you early or late for the meeting?

You are Hours hours and Minutes minutes Early/Late for the meeting.

Advice

We first convert the clock time to 24 hour mode. In this case, since the time on the clock is before 1 pm, we just combine the hours and minutes with a leading 0, to give the time as {clocktime}. In this case, since the time on the clock is after 1 pm we add 12 to the number of hours then combine the hours and minutes to give the time as {clocktime}.

Next we need to calculate the time difference between the two times. Here the earlier time is {earlytime} and the later time is {latetime}.

Adding 1 hour to the earlier time will bring us to {intermediatetime1} which is still earlier than {latetime}, so the later time is more than 1 hour after the earlier time. We then calculate the number of minutes from {intermediatetime1} to {latetime} which gives an additional {differenceMinutes} minutes.

Adding 1 hour to the earlier time will bring us to {intermediatetime1} which is exactly the same as {latetime}, so the later time is exactly 1 hour after the earlier time.

Adding 1 hour to the earlier time will bring us to {intermediatetime1} which is later than {latetime}, so the later time is less than 1 hour after the earlier time. We therefore calculate the number of minutes from {earlytime} to {latetime} which gives an additional {differenceMinutes} minutes.

Since the hours of the earlier time and the later time are both the same we need only find the difference between the minutes of the two times which gives us {differenceminutes} minutes.

Since the earlier time is the time on the clock of the meeting we are {difference} for the meeting
