How long did it take to walk to the swimming pool?
HintsHow many minutes have been added on each time? Place the correct number of minutes into each box.
Between 1:17 and 1:20 there are 3 minutes. How long between the other times?
Remember, add up the minutes to find the total.
SolutionIt took Ajay 48 minutes to walk to the swimming pool.
 There are 3 minutes between 1:17 and 1:20.
 There are 10 minutes between 1:20 and 1:30.
 There are 30 minutes between 1:30 and 2:00.
 There are 5 minutes between 2:00 and 2:05.
 3 + 10 + 30 + 5 = 48 minutes

Can you find the elapsed time?
HintsDo we need to add any hours on?
Add the hours first, then look at the minutes.
You could find the elapsed time using these times. How many minutes between 3:35 and 3:40? How many minutes between 3:40 and 3:48?
SolutionThe correct elapsed time is 1 hour 13 minutes.
 There is 1 hour between 2:35 and 3:35.
 There are 5 minutes between 3:35 and 3:40.
 There are 8 minutes between 3:40 and 3:48.
 5 + 8 = 13
 1 hour + 13 minutes = 1 hour 13 minutes

How long did it take to prepare for the party?
HintsHow much time has passed between the start time and 2:02?
How much time has passed between 2:02 and 2:10?
This is what the first part of the table should look like.
SolutionThe time it took Bella to prepare for the party was 2 hours 23 minutes.
 There are 2 hours between 12:02 and 2:02.
 There are 8 minutes between 2:02 and 2:10.
 There are 10 minutes between 2:10 and 2:20.
 There are 5 minutes between 2:20 and 2:25.
 8 + 10 + 5 = 23 minutes
 2 hours + 23 minutes = 2 hours 23 minutes

Can you find the elapsed time?
HintsDraw your own table to help you find the correct duration. Add small amounts of time until you find the answer.
For the first question, you could start a table like this. How much time has passed from 3:07 to 4:07?
Once you have found the hours, carry on finding the minutes. This one has been continued but make sure you find the minutes until you reach the end time.
Solution The table above shows us that there is 1 hour, 48 minutes between 3:07 and 4:55.
 There is 1 hour between 3:07 and 4:07.
 There are 3 minutes between 4:07 and 4:10.
 There are 20 minutes between 4:10 and 4:30.
 There are 20 minutes between 4:30 and 4:50.
 There are 5 minutes between 4:50 and 4:55.
 3 + 20 + 20 + 5 = 48 minutes
 1 hour + 48 minutes = 1 hour 48 minutes
2.12:57 to 4:15: 3 hours, 18 minutes
3.6:30 to 8:36 2 hours, 36 minutes
4.8:47 to 11:53 3 hours, 6 minutes 
Can you complete the table to find the elapsed time?
HintsHow many hours have passed from 10:30  11:30?
1 hour has passed from 10:30  11:30.
Can you now add the hours and minutes to find the total?
To find the minutes, you need to add 10 + 2.
Solution1 hour 12 minutes has passed from 10:30  11:42.
 There is 1 hour between 10:30 and 11:30.
 10 minutes + 2 minutes = 12 minutes.
 1 hour + 12 minutes = 1 hour 12 minutes
